Testosterone, Free, Bioavailable and Total Blood Test, LC/MS/MS
A Testosterone, Free, Bioavailable and Total Blood Test, LC/MS/MS is helpful in assessing testicular function in males and managing hirsutism, virilization in females.
Description
Generally, testosterone in one's blood will attach to two proteins: albumin and SHBG. There is some testosterone that is not bound to proteins and they are known as free testosterone and albumin-bound testosterone. This type of testosterone is easily used by your body.
Free and weakly bound (bioavailable) testosterone is thought to reflect an individual's biologically active, circulating testosterone.
