Testosterone Panel

A group of hormones and binding proteins that assess testosterone levels, bioavailability, and potential hormonal imbalance.

About

The Testosterone Panel gives you a clearer picture of your hormonal health by measuring not just total testosterone, but also free testosterone (the active form your body can use), SHBG (a protein that can bind and block testosterone), and albumin (a liver protein that affects hormone availability). This combination helps assess how much testosterone is actually available to your body—not just how much you’re producing.

It’s a useful panel if you’re experiencing low energy, reduced sex drive, changes in mood or muscle mass, or if you’re on testosterone therapy and want to track effectiveness. It also helps uncover hidden imbalances that might not show up on a standard testosterone test, guiding better treatment decisions and lifestyle adjustments.

4 Biomarkers Included

Total Testosterone
A hormone involved in muscle maintenance, libido, mood, red blood cell production, and metabolic function.
Free Testosterone (Calculated)
The active form of testosterone calculated by the Vermeulen method to reflect how much your body can actually use.
Sex Hormone Binding Globulin
A protein that binds and stores testosterone and estrogen until it is required by the body.
Albumin
A protein that maintains fluid balance and carries hormones, vitamins, and drugs through your bloodstream.
