Order Testosterone Free & Total Testing | Low TTestosterone is the primary sex hormone in men and plays a supporting role in women. It circulates in the blood in two forms: bound to proteins such as sex hormone-binding globulin (SHBG) and albumin, and unbound, or free. Because only the free fraction is readily available to tissues, measuring both free and total testosterone together gives a more complete picture of hormonal status than either measurement alone.
About Testosterone Free & Total Testing | Low T in Pasadena
Testosterone testing is used to evaluate conditions related to androgen production and regulation in both men and women.
Total testosterone reflects the combined amount of hormone that is bound to carrier proteins and the small fraction that remains free. Free testosterone measures the unbound portion, which is the biologically active form that can enter cells and exert effects on muscle, bone, mood, and reproductive tissue.
Clinicians order these tests when symptoms suggest abnormally low or high testosterone. In men, this may include fatigue, reduced libido, erectile difficulties, loss of muscle mass, or infertility. In women, irregular menstrual cycles, acne, excess hair growth, or signs of virilization may prompt evaluation. The results help distinguish between true androgen deficiency and other causes of similar symptoms.
Because SHBG levels can change with age, body weight, liver function, thyroid status, and certain medications, total testosterone alone can sometimes be misleading. Measuring free testosterone alongside total testosterone helps clarify whether a low total value is due to reduced production or to altered protein binding. Results are interpreted alongside the patient's history, physical exam, and other laboratory findings.
