Order Testosterone TestingTestosterone Testing measures the amount of testosterone in the blood. This hormone is produced primarily in the testes in males and in the ovaries and adrenal glands in females. It plays a key role in muscle mass, bone density, libido, and mood. Testing is used to evaluate symptoms such as fatigue, low sex drive, erectile dysfunction, or infertility, and to monitor hormone replacement therapy.
About Testosterone Testing in Walnut
The Testosterone Panel typically includes total testosterone, which measures both bound and free hormone, and may also include free testosterone or sex hormone-binding globulin (SHBG).
Testosterone exists in the blood mostly bound to proteins, primarily SHBG and albumin. Total testosterone measures all circulating testosterone, while free testosterone measures the small fraction that is unbound and biologically active. Some panels also measure SHBG to calculate a free androgen index.
The sample is collected via a standard blood draw from a vein in the arm. Because testosterone levels fluctuate throughout the day, typically highest in the morning, the collection is often recommended before 10 a.m. No special preparation is usually required beyond following the lab's instructions.
Results are generally available within 1-3 business days. Reference ranges vary by age, sex, and laboratory method, so results should be interpreted by a healthcare provider in the context of individual symptoms and history.
