Hormone imbalance is assessed by saliva and blood testing.

Saliva testing is a convenient, inexpensive, and above all, accurate means of testing steroid hormones. 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.

Saliva testing can be done anywhere anytime. Testing that relies on blood drawn in the doctor’s office makes it harder to obtain samples at specific times (such as in the early morning) or multiple times during the day. In addition, hormones in saliva are exceptionally stable and can be stored at room temperature for up to a week without affecting the accuracy of the result. This offers maximum flexibility in sample collection and shipment.

Hormones tested in thesaliva profiles include:

Blood testing, by either a serum sample or blood spot testing, is also very accurate for hormone testing, but requires that no topical hormones are being used. Thus, it is useful for baseline testing for diagnosis and monitoring of oral therapy only. The use of topical hormone therapy requires saliva testing for accurate monitoring of free hormone levels. Blood testing is not convenient for measuring free Cortisol levels multiple times during the day.
