What is the normal progesterone level at 42 days of pregnancy?

Everyone knows that a certain level of progesterone hormone has many benefits for pregnant women. For example, a relatively high level of progesterone has a significant calming effect on the enlarged uterus, so there is no need to be afraid of early pregnancy. Many women are more concerned about the normal progesterone level at 42 days of pregnancy. We have also consulted experts in obstetrics and gynecology to hear what they say! I hope that everyone can understand it through the editor’s introduction.

Progesterone can relax uterine muscle fibers and reduce excitability. At the same time, it can reduce the sensitivity of the pregnant uterus to oxytocin, reduce uterine contractions, and facilitate the growth and development of the fertilized egg in the uterus. Insufficient progesterone levels may result in threatened miscarriage or miscarriage.

Normal values ​​of progesterone at different stages:

Measurement time Specimen Old system unit Normal value Old-new coefficient Legal unit Normal value New-old coefficient

Follicular phase blood 0.2～0.6ng/ml 3.18 0.6～1.9nmol/L 0.3145

Luteal phase blood 6.5～32.2ng/ml 3.18 20.7～102.4nmol/L 0.3145

7 weeks of pregnancy blood 24.5±7.6ng/ml 3.12 76.4±23.7nmol/L 0.32

8 weeks of pregnancy blood 28.6±7.9ng/ml 3.12 76.4±23.7nmol/L 0.32

Follicular phase blood 24.5±7.6ng/ml 3.12 89.2±24.6nmol/L 0.32

9-12 weeks of pregnancy 38.0±13.0ng/ml 3.12 118.6±40.6nmol/L 0.32

13-16 weeks of pregnancy 45.5±14.0ng/ml 3.12 142.0±43.7nmol/L 0.32

17-20 weeks of pregnancy 63.3±14.0ng/ml 3.12 197.5±43.7nmol/L 0.32

21-24 weeks of pregnancy 110.9±35.7ng/ml 3.12 346.0±111.4nmol/L 0.32

25-34 weeks of pregnancy 165.3±35.7ng/ml 3.12 514.8±111.4nmol/L 0.32

35 weeks of pregnancy blood 202.0±47.0ng/ml 3.12 630.2±146.6nmol/L 0.32

Menopausal blood <1.0ng/ml 3.18 <3.2nmol/L 0.3145

13-36 weeks of pregnancy 55ng/ml 3.12 171.6nmol/L 0.32

Full-term pregnancy blood 26ng/ml 3.12 81.1nmol/L 0.32

Note: Different hospitals use different units for conversion. If the reference value on the test report you get is in ng/ml, for example, the normal value of the old system unit for the follicular phase multiplied by 3.18 is converted to the unit of nmol/L; the normal value of the legal unit for the follicular phase multiplied by 0.3145 can be converted to the old system unit of ng/ml.

In the above article, obstetricians and gynecologists have introduced the progesterone values ​​of pregnant women at different stages. Women who are 42 days pregnant can compare the normal values ​​to know what the normal values ​​are. Then use their own values ​​to compare the normal progesterone values ​​of 42 days of pregnancy to see if it is normal. If it is normal, that is the best. If not, seek medical treatment.
