Testosterone, Bioavailable and Sex Hormone Binding Globulin (Includes Total Testosterone), Adult Male
Acceptable test for the evaluation of suspected hypogonadism in men. Not recommended for use in women and children.
Quantitative Electrochemiluminescent Immunoassay
The concentrations of free and bioavailable testosterone are derived from mathematical expressions based on constants for the binding of testosterone to albumin and/or sex hormone binding globulin.

FDA
Bioavailable testosterone includes free plus weakly bound (non-SHBG bound) testosterone. Bioavailable testosterone is an assessment of the biologically active testosterone in serum.
Please refer to individual components for stability of sample for this test. This test is not recommended for females or children. For testing on females or children refer to Testosterone, Bioavailable & Sex Hormone Binding Globulin (Includes Total Testosterone), Females or Children (0081057).
