Follicle-Stimulating Hormone (FSH) Test

$ 59.0

Evaluate your hormonal health by measuring follicle-stimulating hormone level with an FSH blood test.

Follicle-stimulating hormone (FSH) is a protein produced by the pituitary gland and it has a vital role in your sexual development and reproductive health. FSH helps to stimulate the growth of eggs in the ovaries, which is essential for supporting ovulation and regulating menstruation cycles. As you age, FSH levels typically increase gradually as the ovaries begin to produce fewer eggs.


Our FSH blood test measures FSH level and can provide information on female reproductive health and hormone balance. A change in hormone level can cause symptoms such as irregular periods, decreased sex drive and weight fluctuations. 


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.

Preparation: If you are still menstruating, it is recommended to test on day 3 of your menstrual cycle (cycle day 1 is the first day of your period). If you have no menstrual cycle or have irregular menstrual cycles, you can test at any time.

If you’re taking a supplement containing biotin (also called vitamin B7 or B8, vitamin H or coenzyme R), commonly found in products promoting nail, skin and hair health, we recommend that you wait at least 72 hours from your last dose before taking the test.

What's Tested
  • Follicle-Stimulating Hormone (FSH)

    A hormone that plays a vital role in reproduction by stimulating the growth of eggs in the ovaries and regulating the menstrual cycle. FSH levels in women fluctuate throughout the menstrual cycle, with the highest FSH levels generally detected just before an egg is released by the ovary (also known as ovulation). At menopause, the ovaries become less responsive to FSH and LH hormones, resulting in elevated levels of these hormones.

  • The Labcorp OnDemand Follicle-Stimulating Hormone (FSH) Test measures the level of FSH, a protein made by the pituitary gland, in your blood.


    The FSH test can provide information about your reproductive health and hormonal balance. FSH is a key hormone involved in the menstrual cycle and the production of eggs by the ovaries. The amount of FSH varies throughout a menstrual cycle and is the highest before an egg is released. FSH levels are also highest in women who are menopausal or perimenopausal.


    FSH level will vary based on several factors including your age and if you are taking certain medications (such as birth control). This test provides a snapshot of your hormone level at the time of testing.


    Note: This test does not diagnose or determine the cause of infertility. Follicle-stimulating hormone is typically evaluated in context of other hormone levels such as estradiol.  It is recommended to consult with a healthcare provider 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 adults who are assigned female at birth, the symptoms of hormonal imbalance may include:

    • Fatigue
    • Difficulty sleeping
    • Loss of interest in sex
    • Irregular or no menstrual periods (may be associated with infertility)
    • Heavy menstrual periods
    • Hot flashes
    • Weight gain
    • Mood changes


    If you’re experiencing new, persistent symptoms or have concerns about your FSH level, it’s best to consult with a healthcare provider who can interpret the results in the context of your overall health and medical history.

  • A normal FSH level will vary based on your age and sexual organs, and it’s important to note that reference ranges can vary slightly between laboratories and testing methods.  

    If you have concerns about your FSH level, it’s best to consult with a healthcare provider who can interpret the results in the context of your overall health and medical history.

  • 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, causing bleeding.


    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 when 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.

  • Your testing will be performed in a CLIA-certified clinical laboratory. Labcorp provides leading-edge medical laboratory tests and services through a national network of primary clinical laboratories and specialty testing laboratories. Our labs perform regular quality assurance testing to ensure our results are accurate.

  • Your results will be provided to you through our secure online portal to view or print. Results are also provided to PWNHealth, which provides professional healthcare provider services for OnDemand tests. If you are accessing your results through your Labcorp Patient account, all users linked to the account will have access to all OnDemand test results. Results may also be provided to a local, state, or federal health authority, but only when legally required. For example, many states require the testing laboratory and healthcare provider to report test results for certain communicable diseases, such as sexually transmitted diseases or COVID-19, to local or state health departments.
