A testosterone levels blood test measures the amount of testosterone, a hormone important for sexual development, muscle mass, and mood, in your blood. It is ordered to evaluate symptoms like low sex drive, fatigue, infertility, or erectile difficulties, and to monitor hormone therapy.

What it measures

  • Total Testosterone — The main measure of all testosterone in your blood, both bound to proteins and free.
  • Free Testosterone — The small portion not attached to proteins, which is the active form your body can use.
  • Bioavailable Testosterone — Testosterone that is free plus loosely bound to albumin, easily available to tissues.
  • Sex Hormone-Binding Globulin (SHBG) — A protein that binds testosterone; levels affect how much testosterone is free.
  • Luteinizing Hormone (LH) — A pituitary hormone that signals the testes to make testosterone; helps find the cause of low levels.

Who it is for

A doctor or other clinician typically orders this test when you have symptoms of low or high testosterone, such as changes in sex drive, energy, or mood. It may also be used to monitor testosterone therapy or evaluate infertility.

Preparation

Fasting is not usually required, but testosterone levels are highest in the morning, so a morning blood draw is often recommended. Tell your clinician about any medications or supplements you take, as some can affect results.

Results and what they mean

Results are reported as numbers with a reference range, which varies by age, sex, and lab. Your clinician interprets these numbers along with your symptoms and history. This information is not medical advice; only a qualified professional can diagnose or treat a condition.

Frequently asked questions

Do I need to fast for this test?

No, fasting is not typically needed. However, because testosterone levels change during the day, a morning appointment is often preferred.

How long does it take to get results?

Most results are available within 1 to 3 business days.

Can my medications affect the results?

Yes, some medications and supplements can raise or lower testosterone. Be sure to tell your clinician what you are taking.

What if my results are outside the normal range?

A single out-of-range result does not always mean a problem. Your clinician may repeat the test or order additional tests to understand the cause.
