Testosterone Free & Total, LC/MS-MS, Uncapped

This panel measures both total testosterone (all testosterone circulating in your blood) and free testosterone (the fraction not bound to proteins and available for your body to use). Free testosterone is often the best indicator of how much “active” testosterone your tissues can access. Note: When processed through BioReference lab, this panel also includes a measurement of SHBG (sex hormone–binding globulin), which helps interpret free vs. bound testosterone more precisely. Because this panel uses LC/MS-MS (liquid chromatography–mass spectrometry), it’s highly accurate even at low or very high levels. Unlike some common lab methods, it does not cap out at 1500 ng/dL, making it useful for tracking both deficiency and supraphysiological levels. If you're optimizing performance, energy, libido, or tracking testosterone therapy, this panel gives you the real data that matters.
