Order Testosterone TestingTestosterone testing measures the amount of testosterone in the blood. Testosterone is a hormone produced primarily in the testes in males and in the ovaries and adrenal glands in females. It influences muscle mass, bone density, sex drive, mood, and red blood cell production. Because testosterone levels fluctuate throughout the day and vary with age, testing is typically used alongside a clinical evaluation rather than as a standalone diagnostic tool.
About Testosterone Testing in San Carlos
The testosterone panel provides a direct measurement of circulating testosterone, most often total testosterone, which includes both protein-bound and free hormone.
Total testosterone is the standard initial measurement. It reflects the sum of testosterone attached to sex hormone-binding globulin (SHBG) and albumin, plus the small unbound fraction. Because SHBG levels change with age, body weight, liver function, and other factors, total testosterone alone may not fully capture the amount of hormone available to tissues.
When a clinician needs more detail, the panel may include free testosterone or bioavailable testosterone. Free testosterone measures the unbound portion, while bioavailable testosterone includes free testosterone plus the fraction loosely bound to albumin. These calculations or direct measurements can help clarify results when total testosterone is borderline or when SHBG is expected to be abnormal.
Sample collection for testosterone testing usually involves a blood draw from a vein in the arm. Because testosterone secretion follows a diurnal pattern, with higher levels typically in the morning, collection is often scheduled early in the day. The sample is then processed in a laboratory, and results are reported as a concentration, commonly in nanograms per deciliter (ng/dL) or nanomoles per liter (nmol/L). Turnaround time is generally one to three business days.
