Testosterone, Bioavailable & Sex Hormone Binding Globulin (Includes Total Testosterone), Females or Children : 0081057

Mnemonic: BIO T MASS

Methodology: Quantitative High Performance Liquid Chromatography-Tandem Mass Spectrometry/Electrochemiluminescent Immunoassay
The concentrations of free and bioavailable testosterone are derived from mathematical expressions based on constants for the binding of testosterone to albumin and/or sex hormone binding globulin.
Performed: Sun-Sat
Reported: 1-4 days
Specimen Required: Patient Prep: Collect between 6-10 a.m.

Collect: Serum separator tube or green (sodium or lithium heparin).

Specimen Preparation: 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: 0.4 mL)

Storage/Transport Temperature: Refrigerated.

Remarks: This test is suggested for women and children due to an improved sensitivity of testosterone by LC-MS/MS.

Unacceptable Conditions: EDTA plasma.

Stability (collection to initiation of testing): After separation from cells: Ambient: 24 hours; Refrigerated: 1 week; Frozen: 6 months
