About this test

After ovulation, progesterone rises sharply and stays higher for the second half of the menstrual cycle. It also increases during pregnancy. Because the level depends on cycle timing, the day you test matters. A healthcare provider can advise which cycle day to choose.

For adults 18 and older. Test availability varies by lab location.

Who should take this test?

This test is often used by adults with questions about ovulation, irregular cycles, or fertility, or who are checking a level during hormone therapy with a clinician.

What does this test measure?

Your result shows your progesterone level on the day of the draw, which a healthcare provider can read with your cycle timing to help answer questions about ovulation.

Progesterone
Progesterone is a hormone made mainly by the ovaries after ovulation, and it helps prepare the uterus for a possible pregnancy. Levels rise in the second half of the menstrual cycle and during pregnancy. Because it depends so much on timing, the cycle day of the draw matters.
Why it’s measured: Rises after ovulation, so the cycle day of the draw matters.

What your results tell you

Progesterone is reported as a number and compared with the lab’s reference range. Where you are in your cycle affects how it is read.

  • Your number next to the lab’s reference range
  • Explained in plain language
  • A licensed clinician reviews your order and, if appropriate, orders the test.
  • A lab report you can download and share

A healthcare provider reads progesterone with your cycle dates and other hormones, and decides whether a repeat or added test makes sense.

Questions

Common questions.

Anything else, our care team answers by phone, text, or email.

Progesterone stays low before ovulation and rises sharply after it, so the right day depends on your cycle and the question you are asking.

A healthcare provider can advise which cycle day to test. If your cycles are irregular, ask them how to time the draw, since a test on the wrong day can be hard to read.

After an egg is released, the part of the ovary it came from starts making progesterone. This helps prepare the lining of the uterus for a possible pregnancy. If pregnancy does not happen, progesterone falls and a period follows. During pregnancy, levels keep rising.

The lab notes that DHEA supplements can make this test read falsely high. Hormonal birth control and hormone therapy can also change progesterone levels.

Tell your healthcare provider about any of these. Don’t stop or change any medicine or supplement without talking with your healthcare provider.

One progesterone result is a snapshot. It cannot tell you on its own how fertile you are, and it is not used by itself to say how a pregnancy is going. A healthcare provider reads it with your cycle timing, history, and other tests.
