What this test is

This blood test quantifies free testosterone, the unbound and biologically active form of the hormone. It helps evaluate conditions related to overproduction or deficiency of testosterone. The test may also be used to monitor testosterone therapy.

What it measures

  • Free Testosterone — reflects the unbound, active portion of testosterone in the blood
  • Total Testosterone — reflects the total amount of testosterone, both bound and unbound
  • Sex Hormone Binding Globulin (SHBG) — reflects a protein that binds testosterone and affects free levels

What the test involves

A healthcare professional collects a blood sample, typically from a vein in the arm. The sample is then sent to a laboratory for analysis.

Why it is often ordered

A clinician may order this test to investigate symptoms such as low sex drive, fatigue, or erectile dysfunction in men, or irregular menstruation or excess hair growth in women. It is also used to monitor hormone levels during treatment.

Preparation

How results are reported
