Testosterone, Free and Weakly Bound, With Total Testosterone, LC/MS-MS - (LABCORP)

Description: Free and weakly bound testosterone (FWBT), also referred to as bioavailable testosterone, is thought to reflect an individual's biologically active, circulating testosterone. FWBT includes free testosterone and testosterone that is bound to albumin. FWBT does not include sex hormone-binding globulin-bound testosterone. The SHBG-bound fraction is biologically inactive because of the high binding affinity of SHBG for testosterone. The rapid dissociation of "weakly bound" testosterone from albumin results in the availability of essentially all albumin-bound testosterone for steroid-receptor interaction.

Includes: Testosterone, Free and Weakly Bound, With Total Testosterone, LC/MS-MS

Note: Actual Total Testosterone levels will be provided with this test if levels exceed 1500.

Patient Instructions: If using a testosterone cream please be sure you have not rubbed any into the antecubital area of your arm for the last 24 hours as it can give elevated results.

Estimated turnaround for results is 7 business days. If confirmation testing is required, the estimated time may be extended.
