Why This Biomarker Matters

Testosterone abnormalities affect energy, muscle, bone health, mood, and sexual function. Salivary testing provides a convenient way to monitor hormone status and guide treatment if needed.

Overview

This test measures testosterone levels in saliva, a non-invasive alternative to blood testing. Testosterone is the primary male sex hormone and is also produced in smaller amounts in women. It regulates muscle mass, bone density, energy, mood, and sexual function. Abnormally high or low testosterone can indicate hormone imbalances affecting metabolism, mood, and physical performance. Salivary testosterone reflects the bioavailable hormone level and may be useful for tracking changes over time.
