Salivary Testosterone, LC/MS-MS (Endocrine Sciences)
Measuring testosterone in saliva can be a noninvasive alternative to diagnose and monitor patients with androgen level-related disorders. Salivary testosterone is concluded to be an established means to screen hypogonadism in adult males1 and correlates with plasma free testosterone levels.2-5 Measuring testosterone may be important for identifying women with hirsutism or polycystic ovarian syndrome (PCOS), patients with congenital adrenal hyperplasia (CAH), or males with hypogonadism.
Salivary testosterone must be collected in an appropriate device, as some systems absorb testosterone. Validated devices are the VersiSal® device (provided by LabCorp) or a clean vial with plain saliva (2 mL). Blood in the saliva will invalidate the test because blood contains much higher levels of testosterone. Salivary testosterone is not recommended for children until reference intervals are determined.
Results of this test are for investigational purposes only. The performance characteristics of this assay have been determined by LabCorp. The result should not be used as a diagnostic procedure without confirmation of the diagnosis by another medically established diagnostic product or procedure.
