Gonadotropin Releasing Hormone (GnRH) Blood Test

* This is not a home test kit. You will need to visit a local lab for testing.

Also Known As

Gn-RH, LH RH, Luteinizing Hormone Releasing Hormone

Purpose of the Gonadotropin Test

You’re familiar with estrogen and testosterone, but what about gonadotropin? It’s a hormone that produces two pituitary gland hormones, follicle-stimulating hormone (FSH) and luteinizing hormone (LH), which in turn trigger the release of estrogen and testosterone. In other words, gonadotropin is essential for a fully functioning reproductive system. A GnRH blood test is often used to diagnose or treat infertility or low sex drive in men and women, as well as irregular menstruation in women and testicular issues in men.

Gonadotropin Releasing Hormone (91903)

What Does the Gonadotropin Releasing Hormone Test Measure?

This test measures the levels of gonadotropin in your system.

Who Should Take a GnRH Test?

This testing may be ordered as part of fertility testing; it can be paired with an FSH and LH blood test as well. If you’re experiencing low sex drive or reproductive issues such as sporadic periods, you may need a gonadotropin test.

GnRH Lab Test Preparation

If you take any hormone treatment, you should stop for the 2 days preceding your blood work appointment.

GnRH Testing Results

Normal test results are different for men and women; generally, the reference range for the GnRH blood test is 0 to 10 pg/mL. Your healthcare provider can then determine next steps, depending on where your results fall.
