About Our Testosterone Test - Free

The Free Testosterone Test is a specialized blood test that measures the amount of unbound, biologically active testosterone circulating in your bloodstream. Free testosterone is the form of testosterone that is readily available for the body to use, allowing it to directly influence functions such as energy levels, muscle strength, mood, libido, and reproductive health.

Unlike total testosterone, which measures all testosterone combined, this test focuses specifically on the active hormone, making it especially useful when symptoms are present but total testosterone levels appear normal. Measuring free testosterone provides a more accurate picture of how much testosterone is actually available to your body at the cellular level.

This test is commonly used to evaluate androgen excess or deficiency related to gonadal, adrenal, or hormonal function in both men and women.


What Is Included In This Test?

This test measures:

  • Free Testosterone: The portion of testosterone that is not bound to proteins such as sex hormone-binding globulin (SHBG) or albumin and is immediately available for biological activity

Because free testosterone represents the hormone your body can actively use, this test can help clarify hormonal imbalances that may not be detected through total testosterone testing alone.

Abnormal results may help guide further hormone evaluation, diagnosis, or treatment planning.


Who Should Consider This Test?

The Free Testosterone Test may be helpful for both men and women experiencing symptoms related to hormone imbalance.

Men may consider this test if they experience:

  • Low libido or decreased sex drive
  • Erectile dysfunction
  • Fatigue or low energy
  • Decreased muscle tone or strength
  • Mood changes or irritability
  • Increased body fat or breast tissue
  • Fertility concerns

Low free testosterone in men may be associated with conditions such as hypogonadism, pituitary disorders, or testicular dysfunction.

Women may consider this test if they experience:

  • Irregular or missed menstrual periods
  • Infertility concerns
  • Excess facial or body hair growth
  • Thinning scalp hair
  • Persistent acne
  • Low libido
  • Symptoms related to menopause

This test may also support evaluation of conditions such as androgen excess, adrenal disorders, or hormone-related reproductive concerns.

Common Questions:

How is this test different from a Total Testosterone Test?

A Total Testosterone Test measures all testosterone combined, while the Free Testosterone Test measures only the active, unbound hormone that the body can use.

Getting both tests together is often the best choice if you want the most complete and accurate picture of your testosterone levels.

A Total Testosterone Test shows how much testosterone you have overall, while a Free Testosterone Test shows how much of that hormone is actually active and available for your body to use. Some people have normal total testosterone but low free testosterone due to protein binding, which can still cause symptoms.

Getting both tests helps reduce uncertainty, supports more accurate diagnosis, and allows for better-informed decisions, especially if you’re experiencing symptoms, monitoring treatment, or want a comprehensive hormone evaluation.

Should women get a Free Testosterone Test?

Yes. A Free Testosterone Test can be helpful for women because testosterone plays an important role in libido, energy, bone health, and reproductive function, and abnormal levels may contribute to symptoms such as irregular periods, infertility, acne, excess facial or body hair, thinning scalp hair, or menopausal changes.

Why is free testosterone important?

Free testosterone is the biologically active form of the hormone and directly affects energy levels, libido, muscle strength, mood, and reproductive health.
