  • 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.
