Order Testosterone TestingTestosterone testing measures the amount of testosterone circulating in the blood. Testosterone is a hormone produced primarily in the testes in men and in the ovaries and adrenal glands in women, and it influences muscle mass, bone density, mood, libido, and red blood cell production. Because levels fluctuate throughout the day and vary by age and sex, a blood test provides a direct measurement that can be interpreted against reference ranges established by the laboratory.
About Testosterone Testing in St. Charles
The testosterone profile is a blood test used to assess androgen status.
The panel typically reports total testosterone, which reflects both protein-bound and free hormone. Some profiles also include free testosterone, calculated or measured directly, along with sex hormone binding globulin (SHBG) to estimate the biologically active fraction.
Collection requires a standard venipuncture. Because testosterone secretion follows a diurnal pattern, morning specimens are often preferred, and the laboratory may specify timing in its instructions. Results are usually available within one to three business days.
Reference ranges differ by sex, age, and the assay method used, so results are interpreted in context rather than against a single universal threshold. A clinician evaluates the numbers alongside symptoms, medications, and other laboratory findings.
This RequestALabTest overview explains what Testosterone Testing involves for people in St. Charles, MO.
