The serum progesterone test measures progesterone levels in the blood, a hormone mainly produced in the ovaries. The primary function of progesterone is to prepare the uterus for a potential pregnancy every month. It achieves this by increasing the thickness of the inner lining of the uterus, creating a favorable environment for the fertilized egg to implant in the uterus and develop into a foetus if conception occurs.
This test may be recommended as part of a fertility evaluation if you're experiencing difficulty conceiving. It serves as a reliable indicator of ovulation. The test is typically conducted to determine whether you are indeed ovulating and to assess the proper functioning of your ovaries. Additionally, if you are pregnant, this test can be utilized to monitor the well-being of your pregnancy.
It is recommended:
To identify the cause of female infertility by helping track ovulation (the release of an egg from the ovary).
It helps to diagnose an ectopic pregnancy (a condition where the fertilized egg is implanted somewhere other than the uterus).To monitor the treatment with Progesterone hormone.
It monitors the health of the foetus and placenta, especially in high-risk pregnancies.
To find the cause of the abnormal bleeding from the uterus.
A progesterone test examines the levels of progesterone in your body. Progesterone is crucial for pregnancy because it prepares the uterus for the implantation of a fertilized egg, prevents uterine contractions, and prepares the breasts for milk production in one phase of the menstrual cycle.1 As a result, analyzing progesterone levels is instrumental for detecting issues related to pregnancy and ovulation.
Progesterone levels within the normal range depend on the menstrual cycle or pregnancy phase. Please note that these values are for women unless otherwise specified:
Pre-ovulation phase: Less than 3.18 nmol/L (1 ng/mL)
Mid-cycle: 15.90–63.60 nmol/L (5–20 ng/mL)
Postmenopausal period: Less than 3.18 nmol/L (1 ng/mL)
First trimester of pregnancy: 35.62–286.20 nmol/L (11.2–90.0 ng/mL)
Second trimester of pregnancy: 81.41–284.29 nmol/L (25.6–89.4 ng/mL)
Third trimester of pregnancy: 152.64–477 to over 954 nmol/L (48–150 to over 300 ng/mL)
For men, the normal progesterone value is less than 3.18 nmol/L (1 ng/mL).
