Description:

Testosterone Bioavailable, Free and Weakly Bound with Total Testosterone, LC/MS Test

This test measures the level of Bioavailable Testosterone as well as Total Testosterone by LC/MS. Testosterone is the primary male sex hormone.  It plays an important role in the development of male reproductive tissues, muscle, and bone mass as well as a number of other health factors.  Testosterone also plays a role in women's health.  Most testosterone in the body is bound to Sex Hormone Binding Globulin.  Unbound or Free Testosterone is biologically active and available for the body to use.  A portion of Testosterone is also bound to albumin in the blood.  This Weakly Bound Testosterone is easily freed for use by the body.  Free and Weakly Bound Testosterone is collectively known as Bioavailable Testosterone.  Measuring Bioavailable Testosterone can give a more accurate level of available testosterone than a standard Free Testosterone Test can.  This test also includes an LC/MS Testosterone which provides a more sensitive measurement than a standard total testosterone test.  The LC/MS test is typically ordered for women or hypogonadal men.  A test which measures Bioavailable Testosterone with a Standard Total Testosterone test is also available.

Bioavailable Testosterone is often ordered as a follow-up to a low result from a Total Testosterone Test, especially if someone also has irregular Sex Hormone Binding Globulin levels.  It may also be ordered to help monitor men who are on testosterone replacement therapy or women with symptoms of excess testosterone production.

Turnaround for this test is typically 3-5 business days. 

Note: Result turn around times are an estimate and are not guaranteed. Our reference lab may need additional time due to weather, holidays, confirmation/repeat testing, or equipment maintenance.
