Testosterone testing measures the concentration of testosterone in the blood. Testosterone is a steroid hormone produced primarily in the testes in men and in the ovaries and adrenal glands in women, and it influences muscle mass, bone density, fat distribution, red blood cell production, mood, and sexual function. Because testosterone levels fluctuate throughout the day and vary with age and health status, testing is typically ordered to evaluate symptoms or to monitor an existing condition rather than as a routine screen for everyone.

About Testosterone Testing in San Marcos

Testosterone testing is used to investigate signs of abnormal hormone production and to track the effects of treatment.

The test usually measures total testosterone, which includes hormone bound to proteins and the smaller free fraction. In some cases, a provider may also request free testosterone or bioavailable testosterone, along with related hormones such as luteinizing hormone and follicle-stimulating hormone, to help distinguish between testicular, pituitary, and other causes of abnormal levels.

Sample collection involves a standard blood draw, most often from a vein in the arm. Because testosterone follows a daily rhythm, with higher values typically in the morning, collection timing can matter, and a provider may recommend a morning draw. The sample is then analyzed by an immunoassay or, for greater precision, by mass spectrometry.

Results are generally available within one to three business days, though the exact timeframe depends on the laboratory and the specific assays ordered. Reference ranges vary by age, sex, and the laboratory performing the test, so results should be interpreted by a qualified healthcare professional in the context of symptoms, medical history, and any prior testing.
