Some ADVANTAGES of saliva testing compared to serum testing:
Estrogens, progesterone, testosterone, DHEA-S and cortisol are routinely measured in saliva. 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 has demonstrated clear correlations between salivary hormone levels and reported symptoms.
Why do we ask for a larger sample volume? Steroid hormones are secreted in a bursts and pulses by various glands throughout the body. The more saliva that is collected, the more the effect is averaged out, and thus the results become more reliable and of the highest clinical relevance. READ MORE
