How to check whether progesterone is normal

It is very important for pregnant women to check whether the progesterone level is normal during pregnancy. If a woman lacks progesterone, it can easily lead to fetal instability or even induce miscarriage. Therefore, progesterone should be supplemented in time before and in the early stages of pregnancy. Prenatal check-ups should also be carried out in a timely manner in the early stages of pregnancy to prevent this situation from occurring. Let’s take a look at how to check whether progesterone is normal.

How to check whether progesterone is normal

Many people know the importance of progesterone and the necessity of progesterone testing, but when they get the test report, they are dumbfounded. What do these numbers mean? Do they have to keep asking the doctor?

First of all, when it comes to progesterone, we must immediately know that the average progesterone value of normal pregnant women is 25ng/ml (80.3nmol/L), so this value is very important. If the progesterone value is ≥25ng/ml, it is normal; if the progesterone value is between 15-25ng/ml, it indicates luteal insufficiency and progesterone treatment is needed with a higher success rate; if the progesterone value is ≤15ng/ml, the treatment is of little significance and the pregnancy needs to be terminated as soon as possible. Moreover, studies have shown that a decrease in progesterone in pregnant women can lead to threatened abortion and inevitable miscarriage, and exogenous progesterone supplementation is needed to maintain early pregnancy.

In addition, in the early stages of pregnancy, the progesterone level should remain elevated. If two progesterone test results are compared and the progesterone level is found to be lower than the previous one, then there is a high probability that an ectopic pregnancy has occurred or there is a problem with the embryonic development, and further examination is required. The β-hCG value of a normal intrauterine early pregnancy should increase significantly from the 9th to 11th day, and can double every day thereafter. However, the hCG secretion of an ectopic pregnancy is low, and the daily increase is smaller.

If the progesterone level increases significantly during 9-32 weeks of pregnancy, it can reach 10-100 times that of normal people. The level in twin pregnancy is higher than that in single pregnancy. If the progesterone level in early pregnancy is lower than normal and continues to decrease, miscarriage or embryonic arrest may occur, and the fetus will need to be preserved.

Finally, when you receive the progesterone data checklist, you can compare it with the "normal values ​​of progesterone in different periods". For example, the progesterone value on the test report is 88.21±23.7nmol/L. After comparison, it can be inferred that the expectant mother is about 8 weeks pregnant. ...

What does a progesterone test mean?

Maybe many people don’t understand what progesterone testing is and whether it is necessary at the beginning. In fact, progesterone, also known as progesterone, abbreviated as "P" in English, is also called progesterone, progesterone, progesterone, progesterone, progestin or progesterone. It is a steroid involved in female menstrual cycle, pregnancy and affects the embryos of humans and other animals. It is produced by the corpus luteum of the ovary in early pregnancy. During pregnancy, progesterone is an important hormone that supports the early growth and development of the fetus. High concentrations of progesterone have a significant calming effect on the enlarged uterus and are also very important for supporting early pregnancy.

Therefore, the progesterone test is to test the progesterone value, and this test can show the basic situation of pregnancy. During pregnancy, hCG stimulates the corpus luteum to produce progesterone; during weeks 7-9, this gradually transitions to the production of the placenta, also known as luteal placental transfer; during weeks 10-11, the production of progesterone by the placenta increases significantly, at which time the trophoblastic cells of the placenta take over from the corpus luteum to produce progesterone and maintain pregnancy. Progesterone testing during pregnancy is mainly used to understand the function of the corpus luteum and whether the ovaries are ovulating.
