What is the normal progesterone level at four weeks of pregnancy?

It is common knowledge that you need to have regular prenatal checkups during pregnancy so that the baby is born healthy. One of the data that pregnant women are most concerned about is progesterone, which is directly related to the health of the child. So what is the normal progesterone level four weeks into pregnancy? Next, let’s follow authoritative experts to learn some common sense. I hope that through my introduction, everyone can have a general understanding.

Please calculate the gestational age from the first day of the last menstrual period.

Normal reference value:

HCG (IU/L) in weeks of pregnancy

0.2-1 week 5-50

1-2 weeks 50-500

2-3 weeks 100-5000

3-4 weeks 500-10000

4-5 weeks 1000-50000

5-6 weeks 10,000-100,000

6-8 weeks 15,000-200,000

February-March 10,000-100,000

Below is a list of normal progesterone and HCG values ​​during pregnancy. Please note that the units are unified. Special note: mIU is the same as mU (the I in the middle of MIU means international unit). 1u/ml=1000mu/ml=1000mIU/ml

The normal progesterone value at four weeks of pregnancy is mainly introduced in the above article. It is hoped that pregnant women can test their progesterone values ​​regularly during pregnancy. Of course, it is best if it is within the range. If you find that it is not within the range, you need to find a way to deal with it. The specific details should be determined by the doctor, and you just need to cooperate with them.
