SALIVA VERSUS SERUM HORMONE TESTING
Saliva testing is proving to be the most reliable medium for measuring adrenal/ovarian hormone levels.
Hormone levels in saliva accurately represent the amount of hormone delivered to receptors in the body, unlike serum which represent
hormone levels that may or may not be delivered to receptors of the body. Clinically, it is far more relevant to test the amount of hormones delivered to the tissue receptor as this is a reflection of the active hormone levels of the body.
The majority of hormones in the blood exist in one of two forms, free (5%) or protein bound (95%). While 95% of the hormones in the body are protein bound, it is only the 5% free hormones that are biologically active.
Saliva measures the free bioavailable hormone levels in the body, while serum measures only the protein bound non-bioavailable hormone levels. Therefore, serum is a much less accurate measurement than that of saliva when assessing functional hormone levels. This is why we use saliva hormone testing instead of sending you to the lab to have blood drawn!
Saliva Measures the “Unbound” Biologically Active or Free Hormone Levels in the Body:
When blood is filtered through the salivary glands, the bound hormone components are too large to pass through the cell membranes of the salivary glands.
Only the unbound hormones pass through and into the saliva. What is measured in the saliva is considered the “free”, or bioavailable hormone, that which will be delivered to the
receptors in the tissues of the body.
Serum Measures the “Protein Bound”
Biologically Inactive Hormone Levels in the Body:
In order for steroid hormones to be detected in serum, they must be bound to circulating proteins. In this bound state, they are unable to fit into receptors in the body, and therefore will not be delivered to tissues. They are
considered inactive, or non-bioavailable.
Only Saliva Testing Measures Topically Dosed Hormones: The discrepancy between free and protein bound hormones becomes especially important when monitoring topical, or transdermal, hormone therapy. Studies show that this method of delivery results in increased tissue hormone levels (thus measurable in saliva), but no parallel increase in serum levels. Therefore, serum testing
cannot be used to monitor topical hormone therapy.
Our testing kit checks the following key adrenal hormones: estradiol (estrogen), progesterone, testosterone, Dhea, Cortisol (am)
Whether you are checking your hormones for the first time or if you are monitoring the effectiveness of your natural bio-identical hormone creams... saliva is the best way to test.
This kit is sent you to your home. You simply follow the easy directions on collecting saliva (stated in the kit) and it is then sent via UPS (pre-paid postage) directly to our lab for evaluation. We recieve the results in 5 working days after their receipt of your saliva. Once we have the results we will contact you and set up an appointment to consult and go over all results and our recommendations for supplementation as needed.
