Luteinizing Hormone (LH) Blood Test

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

Also Known As

Interstitial Cell-Stimulating Hormone (ICSH), Lutropin

Purpose of the LH Test

Luteinizing hormone (LH) is produced in the brain’s pituitary gland and plays a significant role in reproductive health for both women and men. LH starts its work in puberty, when levels rise and they trigger estrogen production in girls and testosterone in boys. And you need LH to get pregnant because it helps with ovulation and sperm formation. That’s why an LH test can be an important component of fertility testing for men and women.

What Does the Luteinizing Hormone Test Measure?

This test measures the LH levels in your blood. You can test LH on its own or alongside follicle-stimulating hormone (FSH), which is another critical reproductive health hormone.

Who Should Take a Luteinizing Hormone Blood Test?

Men and women can take this test to help determine the cause of infertility; women can also use it to time their cycles and improve their odds of conceiving. LH blood work may also be recommended if someone is experiencing:

  • Delayed or early onset of puberty
  • Irregular menstrual cycles
  • Symptoms associated with menopause or perimenopause
  • Fatigue, weakness, or weight loss, which are symptoms linked to pituitary gland dysfunction

LH Lab Test Preparation

You don’t need to fast or complete any other special requirements before getting your blood drawn for the luteinizing hormone test.

LH Lab Results

Women’s results are influenced by their current life stage and, if menstruating, where they are in their cycle when tested. Generally, normal ranges for premenopausal women are 5 to 25 IU/L and 21.9 to 56.6 IU/L at the height of the cycle. LH levels for postmenopausal women should range from 14.2 to 15.3 IU/L. Men’s normal levels can range from 1.24 to 8.6 IU/L.
