Saliva Tests

Estrogens, progesterone, testosterone, DHEA-S and cortisol are routinely measured in saliva at ZRT. Steroid hormones in the bloodstream are mostly (95-99%) bound to carrier proteins, and in this form are unavailable to target tissues. Only the unbound fraction freely diffuses into tissues, including the salivary gland. Hormone levels in saliva therefore represent the quantity of the hormone that is currently available to target tissues and actively exerting specific effects on the body. Research at ZRT has demonstrated clear correlations between salivary hormone levels and reported symptoms.
