Order Testosterone Free & Total Testing | Low TTestosterone is a hormone produced primarily in the testes and, in smaller amounts, in the ovaries and adrenal glands. It influences muscle mass, bone density, fat distribution, red blood cell production, mood, and sexual function. Because testosterone circulates in the blood in two forms — attached to proteins and unbound — a complete picture often requires measuring both. The Testosterone Free & Total Test evaluates these two fractions together, offering a more detailed view than either measurement alone.
About Testosterone Free & Total Testing | Low T in Vista
This test measures both the total amount of testosterone in the blood and the portion that is not bound to proteins.
Total testosterone reflects the combined sum of testosterone attached to carrier proteins, mainly sex hormone-binding globulin (SHBG) and albumin, plus the small fraction that circulates freely. Free testosterone refers only to the unbound portion, which is biologically active and available for tissues to use.
Clinicians may order this combined test when symptoms suggest an imbalance, such as persistent fatigue, reduced muscle mass, low libido, or unexplained changes in mood. In women, it can also be part of an evaluation for irregular menstrual cycles, acne, or excess hair growth. Because SHBG levels can shift with age, liver function, thyroid status, and body weight, total testosterone alone can sometimes be misleading; adding free testosterone helps clarify how much hormone is actually available to the body.
Results are typically interpreted alongside a person's symptoms, medical history, and other laboratory findings. A single out-of-range value does not automatically confirm a diagnosis, and reference ranges vary by laboratory and by the individual's age and sex. Follow-up testing or additional hormone panels may be recommended depending on the initial results.
