Order Testosterone TestingTestosterone Testing, often ordered as a Testosterone Profile, is a laboratory panel used to measure the amount of testosterone present 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 plays a role in muscle mass, bone density, mood, and reproductive function. Because testosterone levels fluctuate throughout the day and vary by age and sex, the panel is interpreted alongside the broader clinical picture rather than as a single stand-alone number.
About Testosterone Testing in O'fallon
The Testosterone Profile measures the concentration of testosterone in a blood sample, most commonly as total testosterone.
Total testosterone reflects the combined amount of testosterone that is bound to carrier proteins and the smaller fraction that circulates unbound. Some panels also report free testosterone, which represents the unbound portion that is biologically available to tissues, or bioavailable testosterone, which includes the unbound fraction plus that loosely bound to albumin.
The sample is collected by a standard venipuncture, typically from a vein in the arm. Because testosterone secretion follows a diurnal pattern, with higher concentrations usually observed in the morning, collection timing is often specified by the ordering clinician. The specimen is then processed and analyzed using immunoassay or mass spectrometry methods, depending on the laboratory.
Results are generally reported within one to three business days. Reference ranges differ by sex, age, and the assay used, so values should be reviewed in the context of the individual's health history and any symptoms that prompted testing. Follow the lab's instructions regarding preparation before the collection.
