What does the Testosterone, Bioavailable (calculated) test measure?

Q: What is the reference range for Testosterone, Bioavailable (calculated)?

The standard reference range for Testosterone, Bioavailable (calculated) is Adult men ~110–575 ng/dL; method-dependent # REVIEWER FLAG: Reviewer to confirm Access Medical Laboratories method and range.. Reference ranges vary by laboratory and assay platform — interpret in context of the issuing laboratory's stated range.

Testosterone, Bioavailable (calculated) (Bioavailable T) is a clinical biomarker used in male-hormones assessment. Bioavailable testosterone comprises the free fraction plus the loosely albumin-bound fraction, which dissociates readily and is accessible to tissues. It is measured in 1 laboratory test on BiomarkersLabs.com.

What is Testosterone, Bioavailable (calculated)?

Bioavailable testosterone comprises the free fraction plus the loosely albumin-bound fraction, which dissociates readily and is accessible to tissues. It is derived by ammonium sulphate precipitation of SHBG-bound hormone or calculated from total testosterone, SHBG, and albumin, and reflects the portion of circulating testosterone realistically available for biological action.

Why is Testosterone, Bioavailable (calculated) measured?

Bioavailable testosterone captures both the free and the readily dissociable albumin-bound fractions, making it valuable where SHBG abnormalities render total testosterone unreliable. It is used alongside free testosterone in the same SHBG-altered or equivocal scenarios to characterise true androgen availability.
