HCG: table for weeks of pregnancy. The norm of hCG during pregnancy

Many girls, sitting in front of the obstetrician-gynecologist's office, are reviewing their pregnancy history. She is practically all pasted with results of analyzes of urine and blood. Everyone wants to understand, is everything ok with the baby? But, alas, all the hieroglyphs, figures, abbreviations can not be disassembled to the common man. Flipping through the story, almost everyone pays attention to the abbreviation HCG. Many of these letters are of interest. And this is just a hormone that shows pregnancy by week.

What does hCG mean?

After the detection of the delay, many girls go to take tests to determine the level of the hormone hCG in the blood. The analysis will show the changes even with a delay of only one or two days. HCG is a glycoprotein consisting of alpha (denoted TTG, FSH, LH) and beta (hCG).

To determine the level of the hormone, doctors use a test for the beta subunit. The pregnancy test also contains this unit, but it is so small that it responds to the onset of pregnancy after 4-5 weeks.

For convenient use there is a table of HCG by day. It shows the age of the embryo in relation to the level of the hormone.

To make sure that the pregnancy is proceeding normally, it is necessary to pass the tests several times, and the level of hCG should not exceed 2000 mU / ml. Do not forget that one analysis can not determine the pregnancy to within a week.

The norm of hCG during pregnancy

If the level of hCG (table by week is presented below) shows less than 25 mU / ml, in this case, you need to re-do the tests. It is better to do this in about 3 days.

The table of hCG for weeks of pregnancy in different medical centers has a slight difference. Most doctors use the mean.

The spread in the norms is quite large. The table of hCG for weeks of pregnancy will relieve the panic of women who, in their analyzes, found deviations in either direction. The table will help determine the level of the hormone from the moment of conception of the child. For this it is necessary to subtract two from the order of the obstetric week. For example, the hormone on the 10th obstetric week corresponds to the 8th week from the moment of conception. The table of HCG-norms given below will become a reference point for women. However, it should be remembered that the final word is left for your attending physician.

What affects the change in the hormone hCG

The growth rate of hCG during pregnancy signals to doctors about normal development or a backwardness from the rate of development. As a rule, at the 14-18th week, doctors prescribe the delivery of repeated tests for the hormone for reinsurance. Since at this time the indicator may indicate the development of pathology in the fetus.

In some cases, when determining pregnancy, a test strip, ultrasound and even a blood test can be mistaken. Quite often hCG (table and its unit of measure) shows a positive result, but pregnancy is absent. This result is influenced by many factors:

• Taking hormonal drugs;
• Recently transferred abortion or childbirth (in which case the hormone level may not yet stabilize);
• The presence of a tumor from the embryonic villi of the chorion;
• Abnormal course of pregnancy.

With an increased level of hCG hormone that does not correspond to the weeks of pregnancy, the reason can be:

• The gestational age does not correspond to the date of conception presumed by the doctor;
• Multiple pregnancies;
• The initial gestation period is accompanied by severe toxicosis;
• Chromosomal abnormalities in fetal development;
• Diabetes maternal diabetes.

If the level of hCG has decreased during the delivery of the tests, the table shows deviations from the norm of more than 50%, in which case the following options are considered:

• Discrepancy in terms of the dates of the actual and anticipated term of pregnancy;
• There is a threat of termination of pregnancy;
• Frozen or ectopic pregnancy;
• Placental insufficiency ;
• Term is more than 41 weeks;
• Fading of the fetus in the last month of pregnancy.

Change in the level of hCG in normal pregnancy

In the absence of different hormonal failures in the female body and the timing of pregnancy, there will be an increase in the hormone every 2 or 3 days. The hCG table by day shows an increase in the hormone, so if the indicator has increased by more than 60% in a few days, do not panic. Pregnancy from the 9th obstetric week or 7th from the moment of conception will show a decrease in blood levels of the hormone.

If a woman has a multiple pregnancy, respectively, and the level of the hormone hCG will increase as many times as the fetus develops.

HCG during a dead pregnancy

Frozen pregnancy is when the fetus dies under the influence of various factors. In this case, the level of the hormone is rapidly decreasing. If there is such a risk, the doctor prescribes the delivery of tests to monitor the dynamics of changes in the hormone hCG.

The table indicates indicators that go beyond the norm? In this case, there is still no room for panic, because the deadline could be set incorrectly. Such cases happen, the doctor additionally appoints ultrasound, and only after its results it is possible to say with accuracy about the development of the fetus. There are also cases in which the pregnancy has already stopped, and the hormone levels continue to grow.

Indicators of hCG at double

Many women, being pregnant, do not even suspect that they have under their hearts more than one baby, and two. Ultrasound on an early date may not show clearly enough the presence of such a pregnancy. In this case, salvage becomes an analysis of the hCG hormone in a double. The table doubles the figures. However, each pregnancy is not similar to the previous one, especially if it is doubled. The value of the hCG table for multiple pregnancies shows a relative value. If the indicators are constantly doubling, be 100% sure that you will have two babies.

For full confidence at an early stage, the dynamics of hCG change is studied. The doctor prescribes the delivery of tests every few days. This should not frighten a woman. This method of research is the only way to determine at an early stage a multiple pregnancy.

The index of hCG at double after IVF

The value of the hCG table during in vitro fertilization will show in a modified state, as the indicators will exceed the standard. This is due to the fact that on the eve of the procedure a woman undergoes hormonal therapy, which prepares the body for bearing. During the procedure, several embryos are inserted into the uterus at the same time. And most women get accustomed to both. Confirm this will help measure the hormone hCG (when doubled, the table shows quite high figures).

What is the test for the determination of hCG? And how to donate blood properly

Passing the analysis to the hormone, a woman can learn about the results of pregnancy after 5-6 days from the moment of conception. This is much more effective than regular express tests.

This test will determine the more accurate date of conception. Quite often, a mother can not accurately name the date of conception, or she calls, but she is wrong. This is quite important, since the parameters of the development of the pod correspond to a certain period. A deviation from the norm can become a signal of the occurrence of complications.

The test scores provide an opportunity to accurately determine the correct development of the child. A sharp increase in the level of hCG indicates a multiple pregnancy, the presence of diseases in the mother or hereditary in the baby. On the contrary, a decrease in the level may become a signal of fetal fading, a delay in development.

To obtain a more reliable result, it is necessary to pass the hormone test correctly. All the details will be told by the doctor. But we must not forget that the tests are given on an empty stomach. It is advisable to donate blood in the morning, but if there is no such possibility, you can surrender during the day, provided that the woman did not eat about 4-6 hours. Blood is drawn from the vein.

It is advisable to exclude physical activity the day before the tests. If hormonal medications are used, tell the doctor, as this affects the accuracy of the analysis.

If you are apprehensive about the results of the tests, do not rush to panic. The doctor can correctly interpret them. If necessary, he will appoint a second test.
