Ordering Recommendation

Recommended initial test in the evaluation of suspected hyperandrogenemia in women and children. Acceptable test for evaluating androgen deficiency in men.

Mnemonic
TESTOS F&T
Methodology

Quantitative High Performance Liquid Chromatography-Tandem Mass Spectrometry/Electrochemiluminescent Immunoassay
The concentration of free testosterone is derived from a mathematical expression based on the constant for the binding of testosterone to sex hormone binding globulin.

Performed

Sun-Sat

Reported

1-4 days

New York DOH Approval Status
This test is New York DOH approved.
Specimen Required
Patient Preparation

Collect between 6-10 a.m.

Interpretive Data

The concentration of free testosterone is derived from a mathematical expression based on the constant for the binding of testosterone to sex hormone binding globulin.

Compliance Statement B: For laboratory developed tests not using a RUO kit, and for FDA approved, cleared or 510(k) exempt assays with alterations. This test was developed and its performance characteristics determined by ARUP Laboratories. The U. S. Food and Drug Administration has not approved or cleared this test; however, FDA clearance or approval is not currently required for clinical use. The results are not intended to be used as the sole means for clinical diagnosis or patient management decisions.

Note

This test is suggested for women and children due to an improved sensitivity of testosterone by LC-MS/MS.  Please refer to individual components for stability of sample for this test.
