A progesterone level blood test measures the amount of progesterone, a hormone involved in the menstrual cycle and pregnancy, in your blood. It is ordered to check whether ovulation has occurred, to evaluate fertility problems or abnormal bleeding, and to monitor early pregnancy or progesterone replacement.

What it measures

  • Progesterone — The main hormone measured; levels rise after ovulation and during pregnancy.
  • Collection timing — The date of the sample relative to your cycle is recorded because it affects interpretation.
  • Related hormones — Sometimes estradiol, LH, or FSH are measured at the same time for context.

Who it is for

A clinician such as a gynecologist, fertility specialist, or primary care provider typically orders this test when evaluating ovulation, menstrual problems, infertility, or early pregnancy concerns.

Preparation

No fasting is usually required. Timing matters: the sample is often drawn about 7 days before the expected next period, or on a day your clinician specifies, so tell the lab the first day of your last period.

Results and what they mean

Results are reported as a number with a reference range that varies by cycle phase, pregnancy, and menopause. A clinician interprets your value along with your symptoms, cycle timing, and other tests. This is general information, not medical advice; discuss your results with a qualified clinician.

When in my cycle should I have the test?

It is often done about 7 days before your expected period, but follow the specific day your clinician recommends.

Can this test confirm ovulation?

Typical turnaround is 1-3 business days, though it can vary by lab.
