Progesterone Test

$ 59.0

Checking progesterone levels can help you track ovulation cycles.

Progesterone is produced primarily by the ovaries and is essential for regulating menstruation and supporting pregnancy. Progesterone levels fluctuate throughout the menstrual cycle and in different life stages. Measuring your progesterone levels can help monitor and track ovulation. Low levels of progesterone may be associated with irregular menstrual periods, mood changes and difficulty in conceiving. Elevated progesterone levels are often a sign of recent ovulation. 


Whether you’re planning for a family, managing your menstrual cycle or seeking to understand your reproductive health, our progesterone blood test can help deliver insights, enabling you to make informed decisions about your health.


Note: This test does not diagnose or determine the cause of infertility. It is recommended to consult with a healthcare provider if you have any questions about your result.

What's Tested
  • Progesterone

    A hormone produced by the ovaries, progesterone is essential for regulating menstruation and supporting pregnancy. During ovulation, when the ovary releases an egg, progesterone levels increase, causing the uterine lining (endometrium) to thicken in preparation for pregnancy. If the egg is not fertilized, progesterone levels drop, the endometrium sheds, and the menstrual period begins. Low levels of progesterone may cause symptoms like irregular periods and mood changes and may be associated with difficulty conceiving. Elevated progesterone levels may indicate recent ovulation. Progesterone levels decrease as you age and enter menopause.

  • The Labcorp OnDemand Progesterone Test measures the levels of progesterone, a type of reproductive hormone, in your blood.


    Progesterone levels fluctuate throughout your menstrual cycle and over your lifetime. Hormone levels can change over time, depending on when you test (the time of day and time during your cycle). This test provides a snapshot of your hormone level at the time of testing. Low levels of progesterone could suggest that you are not ovulating or having ovulation issues which makes it more difficult to conceive, while elevated levels may indicate recent ovulation.1,2


    Note: This test does not diagnose or determine the cause of infertility. A single low progesterone value may not necessarily indicate abnormal ovulation as progesterone levels fluctuate significantly during the luteal phase after ovulation. It is recommended to consult with a healthcare provider to determine the next steps if you have any questions about your result.


    This test is not intended for individuals on hormone therapy or hormonal contraception, as these may interfere with the test results. Hormone levels may fluctuate widely throughout the menstrual cycle, especially during pregnancy and the menopause transition.

  • For those assigned female at birth: The timing of sample collection is important. After ovulation, progesterone levels are typically higher during the luteal phase (the second half of your menstrual cycle). This is why it is recommended that your progesterone test be taken on day 21 of a 28-day menstrual cycle or 7 days before start of your next period.3

  • High progesterone levels don’t typically have a negative impact on your health. Progesterone levels are high during pregnancy. In some cases, high progesterone levels are caused by presence of an ovarian cyst. In rare cases, it can be a sign of ovarian cancer or adrenal gland disorder.2


    Low progesterone can affect your body in several ways, sometimes causing noticeable symptoms. Symptoms of low progesterone include:

    • Irregular menstrual periods
    • Difficulty conceiving
    • Mood changes, anxiety or depression
    • Trouble sleeping
    • Hot flashes
  • Hormone changes in the body trigger each of the four phases of the menstrual cycle: menstruation, follicular phase, ovulation and luteal phase.


    Menstruation is the first phase of the menstrual cycle and is the shedding of the lining of the uterus. During menstruation, the levels of the hormones estrogen and progesterone drop, which causes the endometrium to detach from the walls of the uterus and bleed.


    Proliferative (follicular) phase is the phase of the menstrual cycle that starts after menstruation and ends with ovulation. During this phase, the ovaries produce follicles which develop into a mature egg. The level of estrogen increases, and this helps to thicken the lining of the uterus so that it can support a pregnancy. The follicles grow and mature under the influence of follicle-stimulating hormone (FSH).


    Ovulation phase is when an egg is released from a follicle in the ovary. Ovulation is triggered by a surge in the hormone luteinizing hormone (LH). The egg travels down the fallopian tube towards the uterus, where it can be fertilized by a sperm.


    Luteal phase begins after ovulation where the follicle that released the egg becomes a corpus luteum, which produces progesterone. Progesterone helps to maintain the thick lining of the uterus to prepare for a fertilized egg. If fertilization does not occur, the corpus luteum breaks down and the level of progesterone decreases. This causes the lining of the uterus to shed, and the menstrual cycle begins again.

  • Progesterone levels change throughout your life and typically begin to decline with age as you enter menopause. If you’re experiencing menopause symptoms, our Menopause Test can help you find answers by measuring key hormones, including progesterone, related to reproductive functioning and menopause.

  • Our progesterone test accurately measures the level of progesterone in your blood. On the other hand, a PdG test is a test that detects pregnanediol glucuronide (PdG), the major urine metabolite of progesterone in your urine. While PdG urine tests are qualitative, just identifying if any level is detectable in your urine, a progesterone blood test is quantitative and provides a numeric result that can be a helpful tool in discussing conditions related to hormone imbalances and reproductive issues with your healthcare provider.
