Saliva hormone testing is most useful for uncovering hormone imbalance. For example: discovering a woman has insufficient progesterone to balance high estradiol levels or; that high cortisol levels are interfering with the action of progesterone and testosterone. Once a hormone imbalance has been uncovered, nutritional or bio-identical hormone therapy can be instituted.
Scientific studies have shown a strong correlation between steroid hormone levels in saliva and the amount of hormone in the blood that is active or “bioavailable.”
It is this fraction of total hormone that is free to enter the target tissues in the brain, uterus, skin, and breasts. Unless it is a private practice, conventional medical doctors do not generally offer this test as it is not covered by the federal government.
