Why Order a Progesterone Blood Test?

Who May Need This Test?

This test may be appropriate for:

• Individuals trying to conceive
• People with irregular menstrual cycles
• Patients being evaluated for infertility
• Individuals monitoring hormone therapy
• Pregnant patients whose provider wants progesterone checked
• Anyone whose provider requested a progesterone blood test

Best Time to Test Progesterone

Timing matters because progesterone levels change throughout the menstrual cycle. For many women with regular cycles, progesterone is commonly checked about 7 days before the expected period, often around the middle of the luteal phase.

If your cycle is irregular, if you are pregnant, or if your provider gave you specific instructions, follow your provider's timing guidance.

What Results May Help Show

Progesterone results may help provide information about whether ovulation occurred, whether progesterone levels are consistent with the timing of your cycle, or whether additional follow-up may be needed.

Progesterone results should be interpreted based on your cycle day, pregnancy status, medications, symptoms, and any other tests ordered by your provider.
