Order Testosterone TestingTestosterone testing measures the amount of testosterone in the blood, a hormone that influences muscle mass, bone density, mood, and reproductive function. Because testosterone levels fluctuate throughout the day and vary with age, interpreting results requires attention to collection timing and the pattern of symptoms or clinical findings that prompted the test.
About Testosterone Testing in O'fallon
The testosterone profile typically includes total testosterone, and may add free testosterone or related binding proteins when a more detailed assessment is needed.
Total testosterone quantifies the hormone bound to proteins and circulating freely in the bloodstream. Because a large fraction of testosterone is bound to sex hormone-binding globulin (SHBG) and albumin, total testosterone alone can miss cases where binding capacity is altered. Free testosterone estimates the unbound, biologically active portion and is often calculated from total testosterone and SHBG, or measured directly.
Sample collection is performed by venipuncture, usually from a vein in the arm. Testosterone secretion follows a diurnal rhythm, with concentrations generally highest in the morning and declining through the day, so many clinicians request collection in the morning to reduce variability. The specimen is processed in a laboratory using immunoassay or mass spectrometry methods, and results are reported with reference ranges that depend on age, sex, and the assay used.
Results are generally available within one to three business days. Follow the lab's instructions regarding preparation, and discuss any medications, supplements, or recent illness with the ordering clinician, as these factors can influence testosterone concentrations and the interpretation of the panel.
