Salivary Testing for Steroid Hormone Levels
Salivary testing is proposed as a non-invasive method for measuring steroid hormones which are typically measured in blood and urine samples. These hormones include estrogens, progesterone, testosterone, cortisol, melatonin and dehydroepiandrosterone (DHEA).
Several studies have shown that salivary testing is an effective tool in screening for Cushing syndrome. The late-night salivary cortisol test is used in the home setting by individuals with a regular sleep pattern. Saliva specimen is collected at bedtime and sent to a laboratory. The test detects elevated nighttime cortisol levels which appear to be the earliest and most sensitive markers for Cushing syndrome. If the screening test results are positive, confirmatory tests are then performed.
Salivary hormone testing is also proposed for use by individuals receiving bioidentical hormone therapy, compounded preparations for the treatment of menopause. Proponents of the therapy recommend salivary testing as a means of providing individualized therapy; however, since hormones fluctuate based on diet, hydration and other variables, these conditions are difficult to standardize.Dehydroepiandrosterone (DHEA) and its sulfated analog (DHEAS) are also steroid hormones, principally made in the adrenal cortex. DHEAS is converted into various estrogenic and androgenic compounds. Evidence supporting DHEA and/or DHEAS salivary testing as an effective biomarker is lacking.
Salivary cortisol testing for adrenal incidentalomas and Cushing syndrome is considered medically necessary.
Salivary testing of hormone levels in premenopausal, perimenopausal, and postmenopausal individuals for initiating hormone replacement therapy is considered investigational.
Salivary DHEA and/or DHEAS testing are considered investigational.

The evidence to support salivary testing for reasons other than to screen for Cushing syndrome is of very low quality and conclusions cannot be drawn regarding the accuracy of saliva testing.
