The Testosterone, Bioavailable panel is a blood test that provides a detailed evaluation of testosterone availability and hormone binding in the body. Rather than measuring total testosterone alone, this panel assesses how much testosterone is biologically active and available for use by tissues.
This test is commonly used to evaluate symptoms of androgen imbalance such as low libido, fatigue, infertility, changes in muscle mass, mood changes, or menstrual irregularities. It is especially helpful when total testosterone levels are borderline or do not correlate with symptoms.
The panel includes 4 tests:
Total Testosterone: Measures overall testosterone level in the blood
Free Testosterone: Measures the unbound, active portion of testosterone
Bioavailable Testosterone: Represents testosterone that is readily available for tissue use
Sex Hormone Binding Globulin (SHBG): Assesses hormone binding capacity and influences free hormone levels
