Use in conjunction with free testosterone in the evaluation of suspected hyperandrogenemia in women and children.
Quantitative High Performance Liquid Chromatography-Tandem Mass Spectrometry
Collect between 6-10 a.m.
Serum separator tube or green (sodium or lithium heparin).
Separate serum or plasma from cells ASAP or within 2 hours of collection. Transfer 1 mL serum or plasma to an ARUP Standard Transport Tube. (Min: 0.2 mL)
This test is suggested for women and children due to an improved sensitivity of testosterone by LC-MS/MS.
After separation from cells: Ambient: 24 hours; Refrigerated: 1 week; Frozen: 6 months
