| Clinical Utility | ||
| Testosterone is important in the development of secondary sex characteristics, maturation, and normal function. Because the testosterone bound to albumin (weakly bound form) is as readily available to the tissues as free testosterone, the bioavailable testosterone (the biologically active form of testosterone) includes both the free and albumin-bound fractions. It does not include the testosterone that is bound to SHBG (sex hormone binding globulin) which is not biologically active. | ||
| Specimen and Container Info | ||
|
Specimen Type: Serum Preferred Collection Container: Gold Top, Serum Separator Alternate Collection Container: Red Top, Separator Minimum Acceptable Volume: 1.4 mL |
||
| Processing and Submission Instructions | ||
|
Separator tubes: Contains clot activator and gel for separating serum from cells, but not anticoagulant. Separate serum from cells as soon as the clot has formed (30 minutes). If specimen is centrifuged before clotting is complete, a fibrin clot will form on top of the cell. This may cause the gel barrier to not be intact and could cause improper separation of serum and cells, possibly affecting test results. |
