All about hCG levels. What is hCG (Human Chorionic Gonadotropin)? What does a decrease in hCG tell you?

Diagnosis of pregnancy is extremely necessary. To do this, you can buy a test that is sold at the pharmacy. He will be able to give an answer about the presence of yellow bodies during a urine test.

However, the test does not always give an accurate result. More accurate information can be obtained by taking a blood test for the hormone human chorionic gonadotropin. Its meaning is deciphered using special equipment, so it won’t be possible to do it at home.

About hCG in general

A pregnancy test cannot always determine its presence, especially in the very early stages. To determine pregnancy, a blood test is the most reliable source of necessary information. This is explained by the fact that during the period of conception in female body there is a change in hormonal balance. Initially, this is the appearance of a membrane around the cell, which begins to produce the hCG hormone.

There are cases when a general test does not show the presence of pregnancy, but a blood test makes it possible to reliably determine the level of the hCG hormone and thereby determine the probability of conception already 5 days after fertilization of the egg. In addition, the beta-hCG hormone is an indicator for determining the presence of abnormal fetal development, identifying the threat of miscarriage and establishing exact date pregnancy.

Indications

Blood is always donated for hCG during pregnancy. However, there are indications when doctors also refer for this examination:

long delays in menstruation,
diagnosis of normal fetal development,
suspicion of the possible presence of malignant diseases,
diagnostics during pregnancy, if there is a threat of miscarriage,
to determine pathological conditions of the fetus,
if the doctor suspects a poor-quality abortion.

Donate blood for testing

7-10 days after fertilization of the egg, the amount of the hormone in the blood increases by no more than 5 units. An accurately established day on which conception could have occurred will allow you to confidently perform an analysis two weeks later. The opposite situation indicates the need to reschedule the test 21 days after the end of menstruation. There are times when it has to be repeated after a few days.

After conception occurs, the level of the hormone in a woman’s body will increase all the time. If pregnancy does not occur, then the opposite picture is observed - a decrease in hormone levels.

Decoding the analysis results

After the conception of the egg, the human chorionic gonadotropin hormone will increase until 13 weeks, after this period it will gradually begin to decrease.

As shown by the results of clinical studies in 2012, which were carried out in 95 laboratories using reagents from the Hoffman Roslie concern, the norms of the hormone human chorionic gonadotropin should be within the following parameters:

These research results, shown in the table, are purely for informational purposes, just like the test. This indicator may deviate slightly from the norm and this will not be a cause for alarm.

A detailed examination and quantitative assessment of the beta indicator of the level of the hormone in the blood must be carried out in the first trimester and again in the second. At the same time, the tables enable the doctor to assess the level of this component and determine deviations in the development of the fetus.

Standard indicator of beta hormone in the 1st trimester

Moreover, the test results will be monitored by a doctor who will be able to understand and analyze the dynamics of this indicator.

Human chorionic gonadotropin hormone is an indicator that in the first trimester will allow you to identify and eliminate the threat of miscarriage or if you suspect a frozen/ectopic pregnancy. Since ultrasound of the pelvic organs is not recommended every week, a blood test for hCG levels is an alternative and harmless option for both mother and baby.

Getting ready for research

In medical institutions, to donate blood for the hormone, a sample is taken from a vein. Before this procedure, you should not drink or eat for 8-10 hours. During pregnancy, you cannot be sexually active and avoid significant physical activity.

If you are taking medication, you must notify your doctor before donating blood. The study can be significantly influenced by those drugs that contain the hormone human chorionic gonadotropin.

This is a prerequisite for conducting the study. Violation of this condition can fundamentally distort the results of the study.

Decoding hormone levels

the occurrence of complications during conception associated with fertilization of the egg outside the uterine cavity;
freezing of the fetus;
possibility of miscarriage;
failure of gestation period;
deviations in the structure of the embryonic organ;
the presence of chromosomal pathology.

Only an experienced doctor can decipher the research answers.

If there is an ectopic pregnancy, the egg may be in abdominal cavity or adnexal tubes of the uterus. This means that there are no conditions for normal development of the fetus and indicates serious anomalies.

In vitro decoding will show at the beginning of pregnancy a hormone level reduced by 4 units, and at week 5 this figure will drop sharply. In this case, one study will not be enough; an ultrasound will be required.

When the fetus freezes, the hormone is contained in too small doses, which may additionally be accompanied by a toxic process.

To identify genomic pathologies of the embryo on early stages, namely in the 1st and 2nd trimester, a number of other additional examinations are carried out. This allows you to quickly identify deviations.

If the hormone level is clearly high, one can judge the presence of pathological development of the fetus. However, in this case, the doctor may additionally prescribe an analysis and then interpret it. The reason for a rather high level of hCG may indicate the presence of several embryos in the woman’s body. During periods of severe toxicosis, an increase in the level of this hormone is also observed.

A high rate in men is observed with diabetes or gestosis. This situation may indicate the presence of internal bleeding in the body. Therefore, one study will clearly not be enough. To eliminate the possibility of error, any study can be re-ordered.

In some cases, hCG is elevated, but pregnancy is not diagnosed. This result is observed in the following cases:

taking hormonal medications, contraceptives,
possible presence of chorionic carcinoma (malignant formation),
tumor formations on the ovaries or uterus,
a consequence of abortion or previous pregnancy,
in men, this indicator indicates possible testicular tumors,
the presence of malignant tumors in the digestive system.

The reason for an erroneous study to determine the hormone human chorionic gonadotropin may be:

non-compliance with the rules for delivery and collection of source material;
making an error in determining the deadline;
ovulation disorder;
improper attachment of the embryo.

The level of the hormone in a woman’s body can also change after an abortion or after a miscarriage. An incorrectly performed operation, which indicates unskilled treatment of the uterine cavity. This may be the cause of elevated levels of the hormone human chorionic gonadotropin. Repeat surgery will be required.

After 7 weeks, this indicator returns to normal. The opposite situation suggests that you should consult a doctor and conduct a series of repeated examinations that will identify the cause of such growth.

During menopause or menopause, some women may experience an increased level of this hormone, even by several tens of units. Correct this situation medications, allowing to regulate this indicator to the normal level.

To confirm conception and monitor the normal development of the fetus, a blood test for human chorionic gonadotropin is used in medical practice. The topic of our article today is hCG during early pregnancy. You will also find a table of this hormone by day and much other useful information.

The concept of hCG

HCG or human chorionic gonadotropin is a specific hormone that begins to be produced from the first days after conception. Maximum amount of this substance in the blood of a pregnant woman is observed approximately at the 7th week of gestation. The amount of hormone in urine is usually lower. To confirm conception at home, a woman can use a pharmacy test, the principle of which, in fact, is based on the detection of this hormone.

The structure of hCG includes two subunits - alpha and beta. Alpha are cells that are similar in structure to the pituitary gland, and beta is determined in the study of gonadotropin.

By monitoring the level of human chorionic gonadotropin during pregnancy, it is possible to suspect and identify various disorders in the body of the mother and child. If hCG is detected in the blood of a man or woman in the absence of pregnancy, this may indicate the presence of cancer in the genital area.

Human chorionic gonadotropin is very important.

Without this hormone, it is not possible to successfully bear a fetus. So, hCG has the following functions:

Helps preserve the corpus luteum.
In the first weeks of pregnancy, it stimulates the synthesis of important hormones such as progesterone and estrogen.
Takes part in establishing the function of the child’s gonads and adrenal glands.
If the fetus is male, hCG is involved in the production of testosterone.

If the amount of the substance in question during pregnancy is insufficient, the gynecologist may prescribe the woman drug therapy to maintain the level of human chorionic gonadotropin. Otherwise, the pregnancy may end in miscarriage.

During pregnancy planning and after conception, a blood test for total and free beta-hCG is used in medical practice. General is carried out to confirm the occurrence of conception in the first days after the delay. In the second trimester, this analysis allows us to identify pathologies such as hydatidiform mole, the growth of atypical cells, and fetal development abnormalities. In addition, by assessing the dynamics of the growth of this hormone, the doctor may suspect a frozen or ectopic pregnancy, an incipient miscarriage and other pathologies.

Free beta-hCG is determined during screening in the first and second trimester. Such an analysis allows one to suspect a chromosomal abnormality such as Down syndrome and other disorders in fetal development. If a patient exhibits deviations from the norm, this does not mean a 100% guarantee that the child will have certain disorders. This only gives a reason to classify a woman as a risk group. It is mandatory to test for free beta-hCG in the following conditions:

The pregnant woman is over 35 years old.
The woman already has children with chromosomal abnormalities.
The family has a genetic predisposition to various hereditary diseases of the chromosomal type.

After an abortion, premature birth or miscarriage, this analysis is also mandatory. This is necessary to control the quality of abortion and prevent various complications.

Among men, this type of study is carried out if the patient is suspected of having an oncological neoplasm.

Norm of human chorionic gonadotropin by day in the early stages: table

Below we will consider the hCG table by day from the moment of conception. Here you will find the minimum, average and maximum gonadotropin levels from the first to 41 days after fertilization.

41	28012	65089	125029

The table shows that approximately on day 40, chorionic gonadotropic levels reach their maximum. Later, hCG begins to subside, which is considered a normal physiological state.

Normally, in a woman carrying a baby, the considered indicators rapidly increase at approximately 6-12 weeks, and then begin to rapidly fall. If a woman assumes that pregnancy has occurred, but the test shows negative result, the study should be repeated a week later. By this time, the amount of hCG should reach at least 25 mIU/ml. It is worth noting that when multiple pregnancy human chorionic gonadotropin will be exponentially higher, because each embryo synthesizes a certain amount of this substance.

If the patient has deviations from the norm of more than 20%, she is shown additional medical examination to identify the causes of this condition. Interpretation of the results should be carried out exclusively by a specialist, taking into account data obtained as a result of other types of examination expectant mother.

Causes of low levels of human chorionic gonadotropin

HCG levels below normal may indicate various disorders in fetal development. Let's look at a few common reasons:

A low level of the hormone is observed during a frozen pregnancy, when the fetus for some reason stops its development.
Error in calculation between embryonic and obstetric periods.
Insufficient concentration of the substance in question is noted when ectopic pregnancy. This is a condition when a fertilized egg is implanted not in the uterus itself, but, for example, in the ovary or on the cervix.
Often, low levels of the hormone occur during IVF after embryo transfer.
The deviation is also diagnosed when the fetus freezes or the child has various developmental anomalies.
Low hCG is diagnosed when there is a threat of miscarriage.

In the third trimester, a high percentage of this substance is observed during prolonged pregnancy, which requires urgent stimulation of labor.

To confirm or refute various abnormalities in the fetus with low hCG levels, the pregnant woman is prescribed an ultrasound examination and additional tests.

Pregnant women may experience not only a low level of the hormone in question, but also its high levels, which often also indicates various abnormalities. A blood test helps determine the amount of hCG. It can be taken both at the state and at private clinic. So, what violations does it indicate? high level human chorionic gonadotropin in a woman while pregnant:

Oncological neoplasms in women in the genitourinary system.
Choriocarcinoma is a tumor of the trophoblastic type, resulting from the transformation of the chorionic epithelium into a malignant formation.
Hydatidiform mole is a condition in which a fluid-filled cavity forms in place of the embryo.
Chromosomal abnormalities - Down syndrome, severe pathologies of the fetal brain and heart.
High levels of the hormone often occur with twins or triplets, that is, if several embryos develop in the womb at once. This is a completely normal physiological state.

Another reason is severe pathologies endocrine system mother and fetus.

If a high level of hCG is detected in the patient’s blood, the expectant mother is required to undergo additional medical examination and assessment of the gonadotropin level over time.

Reasons for high hormone levels in maternal health

As we have already found out, a high level of the hormone in an expectant mother can be observed normally during a multiple pregnancy. Sometimes such indicators are also observed in the following conditions:

Severe toxicosis, which often occurs in the early stages.
For various abnormalities in embryo development.
Late toxicosis– gestosis, which develops on later.
Prolonged, that is, post-term pregnancy.
The mother has diabetes mellitus or other diseases of the endocrine system.

In addition, deviations from the norm often occur when a woman takes histogenic medications.

If during the triple test such abnormalities were discovered in the mother, she is identified as a risk group and additional studies and ultrasound are prescribed.

The gynecologist’s task when a patient comes to him is to correctly calculate the duration of pregnancy. This period is usually calculated from the first day of the last menstruation or the day of ovulation in case of a regular cycle for the expectant mother.

Sometimes it may be that the doctor incorrectly calculates the timing. This can happen, for example, if ovulation is late or if a woman does not remember the date of her last menstrual period. Actually, if the period is calculated incorrectly, the HCH will deviate from the norm. To confirm the timing of pregnancy, an ultrasound examination must be performed.

Violation of the level of human chorionic gonadotropin during frozen and ectopic pregnancy

Low levels of hCG are quite often observed in pathologies such as frozen or ectopic pregnancy. Let's look at these states in more detail.

If the development of the embryo stops for some reason, the level of gonadotropin will gradually decrease. In this case, a miscarriage does not necessarily occur. The embryo may remain in the uterine cavity for some period. Sometimes ovum continues to develop, but no embryo is observed in it. This diagnosis is most often made to the patient in the early stages before the 10th week, however, fetal death can occur at a later stage. If during the analysis the hCG level decreases, the woman is usually prescribed a repeat test after two days. If gonadotropic production stops, fetal death is confirmed. Treatment depends on the stage of pregnancy. The girl is shown medical abortion or curettage of the uterine cavity.

If fetal death occurs in the later stages, the patient is prescribed artificial induction of labor followed by hormonal therapy.

If the attachment of a fertilized egg occurs outside the uterine cavity, the hCG level will remain within normal limits or gradually decrease. In this case, the embryo can attach to the fallopian tube and develop there until a certain period. Pathology can be confirmed using ultrasound examination. From the first days after such a process, the hormone level will be minimal. Reviews from women also indicate that the second line on the test may have a paler color.

If the diagnosis is confirmed, the patient is indicated for urgent surgical intervention. If the period is long enough, there is a risk of rupture of the fallopian tube, which can even lead to the death of the patient. To prevent such dangerous complications The girl is advised to visit the hospital immediately after confirming conception at home using a test.

You can find out more information about ectopic pregnancy by reading one of ours.

What fetal abnormalities are indicated by abnormal levels of human chorionic gonadotropin?

Together with other markers, deviations in hCG levels may indicate various pathological conditions in the fetus. To identify developmental disorders of the child throughout the entire period, two screenings are carried out:

From 8 to 14 weeks. Here indicators such as plasma protein A and hCG are assessed.
From 16 to 20 weeks. Here the woman undergoes a triple test, which is used to determine ACE, hCG and extrol-A.

These markers, when examined comprehensively, allow us to suspect the following anomalies:

If the chorionic gonadotropic level exceeds more than 2 times, a chromosomal abnormality such as Down syndrome can be suspected.
If all indicators are reduced, Edwards and Patau syndrome is suspected.
With all normal values, except for hCG, Turner syndrome is suspected.
Abnormalities in these tests also often indicate developmental disorders nervous system fetus, heart and blood vessels of the child.

Medical research data obtained during laboratory tests are assessed by the leading gynecologist in conjunction with other characteristics of the patient.

These include the woman’s age, the presence of concomitant acute or chronic diseases and other characteristics. If necessary, a woman is prescribed drug treatment or artificial termination of pregnancy.

Let's sum it up

Human chorionic gonadotropin is a hormone that is very important during pregnancy. This indicator allows you to assess whether the fetus is developing normally, suspect and identify various disorders in the baby, and carry out the necessary correction of the condition of the mother and child with the help of medications.

(hCG) is a certain hormone protein that is produced by chorionic cells during pregnancy after implantation of the embryo into the uterus. HCG results during pregnancy make it possible to determine pregnancy early (6-10 days after fertilization). HCG consists of two units - alpha and beta. To obtain the test result, beta (beta-hCG) is required in the blood of a pregnant woman. How to understand the results of hCG tests, where to go to donate blood for the pregnancy hormone and then receive a competent hCG interpretation of the results.

HCG blood test - interpretation

Monitoring the result of this test is mandatory because the correct level of the hCG hormone is very important for the normal development of pregnancy.

The hCG result during pregnancy may be overestimated in case of multiple pregnancy (proportional to the number of fetuses), diabetes mellitus, fetal pathologies (multiple fetal malformations, Down syndrome), toxicosis, as well as in case of incorrectly determined gestational age.

The result of a blood test for hCG may be lowered in cases of frozen pregnancy, delayed fetal development, threat of miscarriage, placental insufficiency. The result may also be lowered.

HCG analysis results transcript

How to understand the results of hCG?

At the same time, the norms for deciphering hCG during pregnancy are given for the duration of pregnancy not according to the timing of the last menstruation, but from the moment of conception. In every laboratory b-hCG decoding is carried out according to its own standards, so the results you obtain may differ slightly from those indicated. Therefore, when donating blood for hCG, the results must be deciphered in the same laboratory.

Decoding hCG during pregnancy throughout the entire period will show a gradual increase in indicators. So, during the first trimester, the result of the hCG analysis will increase very quickly, almost doubling every 2-3 days.

At 10-12 weeks, the transcript of the hCG analysis during pregnancy will show the highest hCG level. Then decryption hCG results will show a slow decrease in indicators to a certain level, which remains constant until the birth itself.

Table of hCG growth results by DPO days (day after ovulation)

If in the body of a man or woman, when donating blood for tumor markers, the decoding of hCG gives increased results, this is typical for embryonal types of cancer or ovarian cancer.

: everything in him “adjusts” to the development of a new little life in him. From now on, each of the systems and their components will be ready to signal in the blink of an eye if something threatens the development of this new life. One of the most amazing metamorphoses in the process of the formation and development of a baby is the dramatic change in a woman’s hormonal background, to the point that her body now begins to produce hormones in large quantities, the level of which is extremely low before fertilization and after the birth of the child.

These hormones include human chorionic gonadotropin, which is usually abbreviated as hCG. So, hCG during pregnancy is one of those informative indicators with which specialists have the opportunity to suspect any abnormalities in the development of pregnancy or, by monitoring the level of human chorionic gonadotropin, confirm the norm. In addition, it is hCG that becomes the substance that colors the homeb strip: already on days 6-8, human chorionic gonadotropin is present in the urine. This is because the tissues of the fetus, or rather the chorion, which in the future will turn into the placenta, begin to intensively produce it. But the level of hCG in the blood during pregnancy is much higher than in the urine, and therefore tests to determine human chorionic gonadotropin in the body of a pregnant woman are carried out precisely when examining blood samples.

HCG blood test during pregnancy

Human chorionic gonadotropin consists of two particles: alpha and beta, and it is the beta particle that becomes the “informant” that helps doctors track the dynamics of pregnancy. B begins to be produced immediately after implantation of a fertilized egg into the uterus and attachment there to its wall. In the early stages of pregnancy, hCG levels increase rapidly, doubling every two to three days. Its maximum concentration in the blood of a pregnant woman is observed at 7-10 weeks, after which the level of hCG begins to gradually decrease and its levels remain the same almost until childbirth.

The hCG test during pregnancy makes it possible to determine in the early stages some threats to pregnancy, deviations in its normal development and the development of the fetus. Or, conversely, eliminate fears expectant mother on this occasion. An analysis for human chorionic gonadotropin can also tell how many babies live in the mother’s tummy: with the level of hCG is much higher, and it increases in proportion to the number of fetuses.

Elevated levels of hCG during pregnancy can also indicate very dangerous conditions. For example, the concentration of this hormone increases due to endocrine disorders in the mother and possible cancer. In addition, the hCG level is almost twice the normal level in the presence of chromosomal pathologies in the fetus.

But a reduced level of hCG during pregnancy, as well as insufficient dynamics of its increase, can be a sign of an ectopic pregnancy. Also, significantly low concentrations of the hormone are recorded when there is a threat of miscarriage, with placental insufficiency.

To ensure that the hCG test during pregnancy is most reliable, it is taken in the morning, on an empty stomach. If for some reason the blood sample was not taken in the morning and the analysis is carried out at another time, then six hours before the blood collection it is advised not to eat any food. If hormonal drugs are used (even in the recent past), the nurse must be informed. Also, on the eve of going to the doctor to get tested for human chorionic gonadotropin, you will have to avoid physical activity.

How is hCG determined and what are its standards?

The first blood test for hCG concentration is taken 12 days after conception or 3-5 days after a missed period. This is the so-called “defining” test: elevated levels of human chorionic gonadotropin indicate pregnancy. However, at this stage, hCG has not yet reached sufficient concentration, therefore, repeated tests will be carried out a little later.

If we talk about the norms of hCG in blood serum, we can use the following table as a guide:

Non-pregnant women and men - 0-5;

Pregnant women:

1-2 weeks of pregnancy - 25-300 mU/ml;

2-3 weeks of pregnancy - 1500-5000 mU/ml;

3-4 weeks of pregnancy - 10,000-30,000 mU/ml;

4-5 weeks of pregnancy - 20,000-100,000 mU/ml;

5-6 weeks of pregnancy - 50,000 - 200,000 mU/ml;

6-7 weeks of pregnancy - 50,000 - 200,000 mU/ml;

7-8 weeks of pregnancy - 20,000 - 200,000 mU/ml;

8-9 weeks of pregnancy - 20,000-100,000 mU/ml;

9-10 weeks of pregnancy - 20,000-95,000 mU/ml;

11-12 weeks of pregnancy - 20,000-90,000 mU/ml;

13-14 weeks of pregnancy - 15,000-60,000 mU/ml;

15-25 weeks of pregnancy - 10,000-35,000 mU/ml;

26-37 weeks of pregnancy - 10,000-60,000 mU/ml.

By the way, it should be borne in mind that the norms of human chorionic gonadotropin are given for the duration of pregnancy from conception.

Especially for- Tatyana Argamakova

) is a hormone actively produced external tissues embryo in pregnant women. This substance is found in the body of both women and men, but in small quantities. Its increase occurs only during pregnancy in the fair sex.

HCG is divided into two types - alpha hormone and beta hormone. Today we will talk in more detail about the essence of the latter, research on its level in the body and normal indicators. Interesting? Then be sure to read the presented material to the end.

As noted above, human chorionic gonadotropin is a rather specific hormone in the human body. In men and non-pregnant women, it is practically not observed in the urine and is found in extremely small quantities in the blood. Active secretion begins in pregnant girls. The substance is produced by the external tissues of the embryo, and its increased level in urine and blood indicates precisely the fact of pregnancy.

Increased production of the hormone begins within a few days after fertilization of the egg. The structure of hCG contains proteins, amino acids and other biounits that are essential for the fetus. The most extensive division of the hormone is carried out according to its specific properties. The alpha and beta subunits of the hormone are isolated here.

Beta-hCG is the most important type of substance, which begins to be secreted by the tissues of the embryo earliest and in large quantities.

It contains about 150 amino acids and other biological structures. Due to the unique structure and a number of specific properties, it is beta-hCG that helps detect pregnancy in women at the earliest stages of its course. You can determine the fact of fertilization:

through a blood test already on days 5-7 of pregnancy
through a urine test on days 10-12 (all pregnancy tests sold in pharmacies are based on the determination of beta-hCG)

In men and non-pregnant women, the amount of the hormone in the body is small. Its elevated level indicates either pregnancy in the fairer sex, or serious pathologies of the body in both sexes. Normally, an increase in beta-hCG is observed only in women during pregnancy. This should be remembered.

When is the test scheduled?

The beta-hCG test is one of the basic tests for pregnant women. Depending on the individual characteristics In a specific case, such a study can be prescribed to a girl from 3 to several dozen times during the period of gestation.

In addition, the determination of beta-hCG plays an important role in terminating pregnancy. This study helps to track exactly how a woman’s body reacts to the fact of interrupted gestation and whether she needs help.

In situations not related to pregnancy, determination of the hormone level is carried out for preventive purposes. Quite rarely, a profile analysis for beta-hCG is prescribed to people if they suspect:

malfunctions of the organs responsible for the secretion of hormonal substances
improper use of medications that affect the body's hormonal levels

Hormone levels in non-pregnant women and men

As noted earlier, the diagnosis of beta-hCG is carried out using. The examination procedure is identical for pregnant women, men and non-pregnant women. To determine the level of the hormone, a person just needs to visit a diagnostician and submit biomaterial for analysis. The study does not require specialized training.

It is enough to come to the examination hungry and avoid physical and psycho-emotional stress on the eve of the examination. Many doctors also recommend:

Warn the diagnostician about the medications you are taking before the analysis, if any.
Show the specialist the results of previous diagnostics, if any.
For pregnant women, undergo examination in different trimesters of pregnancy in the same laboratory in order to obtain the most reliable and accurate results.
Blood is taken from the ulnar vein of the left arm for testing. As a rule, analysis results are prepared within 3-5 days.

Normal indicators Beta-hCG levels differ between pregnant and non-pregnant women. Thus, for unfertilized women, the norm is considered to be up to 5-6 medical units per milliliter of blood (mU/ml), and for men - up to 3-4. As for pregnant women, their normal values are within wider limits. We'll talk about them further.

Normal beta-hCG levels in pregnant women

The norm of beta-hCG in pregnant women is a highly flexible concept. Normal indicators during pregnancy are different type and depend on its duration. Whether the test results are normal for a particular patient or not is always determined by the specialist observing her.

The average norms look like this:

Week of pregnancy	Beta-hCG level, mU/ml
1-2	25-300
2-3	1 500-5 000
3-4	10 000-30 000
4-5	20 000-100 000
5-6	50 000-200 000
6-7	50 000-200 000
7-8	20 000-200 000
8-9	20 000-100 000
9-10	20 000-95 000
11-12	20 000-90 000
13-14	15 000-60 000
15-25	10 000-35 000
26-38	10 000-60 000
