Testosterone, Free & Total w/ SHBG

What it tests for:
This test measures both total testosterone and free (active) testosterone, along with Sex Hormone Binding Globulin (SHBG) — a protein that regulates hormone availability in your body.

Why it matters:

• Total Testosterone: Measures all testosterone in the blood (bound and unbound)

• Free Testosterone: The biologically active form that influences energy, mood, libido, and muscle mass

• SHBG: Controls how much testosterone is available to your tissues; imbalances can affect hormone function even when total testosterone looks “normal”

Who it’s for:
Ideal for men monitoring testosterone optimization, energy, or sexual health, and for women assessing hormonal imbalances, PCOS, or low libido.

This panel provides a comprehensive view of androgen status and helps identify issues related to hormone deficiency or binding imbalances.
