What is the norm of progesterone during pregnancy for weeks?

During the gestation of a toddler, the body of a woman undergoes tremendous changes. The body of the fairer sex becomes more feminine: the belly and hips are rounded, the breast is enlarged. In addition to external transformations, you can note a lot of internal changes. They are completely invisible to an outsider, but appear already in the second week of pregnancy (immediately after the release of the ovum from the female ovary).

Hormonal restructuring in the body of a future mother

Surely everyone knows from the school biology course that immediately after menstruation, the fair sex hormone is produced that affects the growth of the follicles. When the formation reaches a certain size, it breaks and releases the female sex cell. At the place of the burst bag, a yellow body forms , which begins to produce progesterone.

The role of progesterone in the female body

It is worth saying that without the hormone, pregnancy is impossible. Progesterone, produced after ovulation, has a beneficial effect on the genital organ, increasing the endometrium in it. After fertilization, the level of the hormone increases and supports the development of the embryo.

Progesterone increases during pregnancy by week. It maintains the normal tone of the uterine muscle and positively affects the nervous system of the pregnant woman. It is worth noting that the hormone progesterone during pregnancy is initially produced by the yellow body and the adrenal glands. Later, after about 12 weeks, this substance begins to form the placenta formed. In this period, the reverse transformation of the yellow body begins, which completely disappears by the middle of the term.

The norm of progesterone in pregnancy by weeks

Some members of the fair sex who are in an "interesting situation", doctors recommend to take a blood test to determine the amount of some hormones. This is necessary to control the course of pregnancy. With deviations from the norm, a correction is made, which helps to avoid problems in the future. So, what is the norm of progesterone in pregnancy by weeks?

First trimester

This is the most critical period. To begin with it is necessary to say that this time interval includes the following weeks of pregnancy:

• The fifth;
• The sixth;
• The seventh;
• The eighth;
• The ninth;
• The tenth;
• The eleventh;
• The twelfth;
• The thirteenth;
• Fourteenth.

The norm of progesterone during pregnancy by weeks (nmol / l) is in the range from 8.9 to 468.4. During this period of time, doctors carefully control the level of the substance in the blood of a fair sex.

Second trimester

If you did not have a testimony for the analysis of the level of progesterone in the first trimester, then most likely, you already do not get such a recommendation. The same pregnant women, who had to investigate the amount of substance in the blood in the early stages of pregnancy, may have to face such an analysis in this period of time. It is worth saying which weeks of pregnancy includes the second trimester:

• The fifteenth;
• Sixteenth;
• The seventeenth;
• The eighteenth;
• The nineteenth;
• The twentieth;
• The twenty-first;
• The twenty-second;
• Twenty third;
• Twenty-fourth;
• Twenty-fifth;
• Twenty-sixth.

The rate of progesterone in pregnancy is weekly in the range of 71.5 to 303.1 nmol / l. All values that fit within the specified interval are normal.

Third trimester

In this time interval, the analysis for determining the level of progesterone in the blood of the expectant mother is quite rare, but there are generally accepted norms for this period. The third trimester includes the following weeks of pregnancy:

• The twenty-seventh;
• The twenty-eighth;
• The twenty-ninth;
• Thirtieth;
• The thirty-first;
• Thirty-second;
• Thirty-third;
• The thirty-fourth;
• Thirty-fifth;
• Thirty-sixth;
• Thirty-seventh;
• Thirty-eighth;
• The thirty-ninth;
• Fortieth;
• Forty-first;
• The forty-second.

The norm of progesterone during pregnancy varies by a week from 88.7 to 771.5 nmol / l. Values that fit in these indicators are considered normal.

Explanation of results

After you get the result of the analysis, it must be correctly decoded. Preferably, if the specialist does. At the same time, the doctor can give you recommendations and, if necessary, prescribe hormonal medication.

All laboratories, when the patient is given a result, indicate their norms. Without this, it is difficult to determine what is the norm of progesterone during pregnancy by weeks. A table of numerical values is always attached to the result of the analysis. It is for this to determine the value obtained. It is worth saying that in different medical institutions the norm of progesterone during pregnancy by week (table) may differ.

Units

In addition to the standards of the laboratory, it is necessary to take into account the units of measure in which your results are listed. There are times when a person has lost a laboratory table or was simply not given out. What to do in this case?

The norm of progesterone in pregnancy (weekly) ng / ml can be translated into nmol / l. This can help a person understand his analysis and draw the right conclusions. So, if you are presented with a result of 100 ng / ml. How to translate it into a more common unit of measurement?

For correct calculation it is necessary to use the following formula: the numerical value of ng / ml is multiplied by 3.03. As a result, you will get the amount of progesterone in nmol / l. Let's do the calculation: 100 ng / ml multiply by 3.03 = 303 nmol / l.

In a similar way, you can calculate and find out what is the norm of progesterone during pregnancy by weeks (ng / ml).

The first trimester of bearing the child determines the following values: from 12,36 to 80,60 ng / ml.

The second period is in the numerical range from 19.59 to 77.0 ng / ml.

The third trimester is characterized by values ranging from 63.8 to 246 ng / ml.

Deviation from the norm

There are times when the result does not fit into the rules. In this case, progesterone is elevated during pregnancy or is lowered. What can such an indicator mean?

Level up

Such values, which do not fit into the norms, can talk about the incorrectly delivered term of pregnancy. Also, a doctor suspects the formation of a yellow body cyst, improper adrenal work or problems with the placenta.

Lowering the level

Such a result, obtained during pregnancy, can speak of insufficient work of the yellow body. Also, a doctor may suspect problems with the adrenal glands. If you received too low a result, then there may be a threat of termination of pregnancy, and you urgently need a medical correction. To restore the normal amount of substance in the female body, the doctor prescribes hormonal preparations: tablets "Dyufaston", suppositories "Utrozhestan", injections "Progesterone".

How to take the test to get the right result?

Like any blood test, the fence of the material should be performed strictly on an empty stomach. Before passing the analysis you need to keep calm and do not worry. Try to have a good rest before the procedure and do not smoke.

If you take any hormonal drugs, then they must be canceled in a few days. Exceptions are only pregnant women. They can not cancel prescribed medications, especially progesterone. It is worth saying that some hormones are synthetic and not detected in the analysis. Thus, in this case, you will get a result that is truly yours.

Conclusion

Each woman should conduct a study of the level of hormones. This will help control the health of the reproductive system and the general condition of the body. During pregnancy, you should listen to the advice of a doctor and follow his recommendations. Hand over all the prescribed tests and monitor your health. After the conducted research it is necessary to give the doctor an opportunity to decipher your results. Do not self-medicate, especially during the period of bearing the baby. After all, now you are responsible not only for your health, but also for the life of your unborn child.
