SalivaTesting.com - Saliva Hormone Testing & Bioidentical Hormones

Steroid hormones in saliva reflect the portion of circulating hormones in the bloodstream that are unbound by serum binding proteins (free or bioavailable) and therefore are able to enter tissues throughout the body. The salivary hormone values, therefore, reflect the biologically active (the unbound) portion available to target cells. Blood hormone assays reflect both bound and free forms of hormones and do not provide information about the bioavailable fraction of hormone, which can vary depending on the level of blood hormone binding proteins.

Simply put, hormone saliva testing tells us the amount of hormones in our body that are actually usable by our cells; where as blood testing evaluates all circulating hormones regardless of their availability to our cells - and most importantly anyone can do this easy test.
