Order Testosterone TestingTestosterone testing measures the amount of testosterone circulating in the bloodstream. Because testosterone production follows a daily rhythm and varies with age, health status, and time of day, the test is typically interpreted alongside the context in which the sample was collected. It is used to evaluate symptoms that may relate to high or low testosterone rather than as a stand-alone diagnosis.
About Testosterone Testing in Simi Valley
Testosterone is a hormone produced primarily in the testes in men and in the ovaries and adrenal glands in women, with smaller amounts made in other tissues.
Total testosterone measures the combined amount of testosterone in the blood, most of which is bound to proteins such as sex hormone-binding globulin and albumin. Only a small fraction circulates unbound, and that free portion is biologically active.
Because binding proteins can change with age, body composition, thyroid function, liver function, and other factors, a total testosterone result may not reflect the amount of hormone available to tissues. In some situations a provider may also order free testosterone or a calculated free testosterone value.
Testosterone concentrations tend to be highest in the morning and lower later in the day, and they decline gradually with age. Reference ranges therefore depend on the time of collection, the person's age and sex, and the laboratory method used, which is why results are best reviewed by a qualified clinician.
