Drs. R&K Shames Urge Saliva Testing for Hormones:
More effective than standard blood testing
There's a lot of buzz out there right now about bio-identical hormones and new testing opportunities. As a Doctor-Nurse hormone balancing team for over twenty years, we have some helpful news that may make it easier for you to understand the best methods for checking your hormones.

When it comes to testing hormones, the conventional lab blood draw levels of your hormones in the body are often inaccurate and misleading. Why? Hormones don't float free in the blood; they are tightly bound to blood proteins (the binding globulins).

The Problem:

When tested with the older standard blood draws, hormones that shows up in the blood draw are not actually available to the tissues that use it.  Hormones that are bound and unavailable to the tissues show up as a large part of your hormone test result. Therefore, a standard blood test is not accurate unless you also measure the level of the "binding proteins", and know the degree of affinity. In other words, what they are measuring is most often not the amount of hormone that is actually free and ready to go to work in your tissues.  

The Solution

A much superior way to test for these hormones (our sensitive messenger chemicals) is to check the amount that is unbound and ready to go to work in your body. This is called measuring the " free fraction" which is what saliva testing does. The steroid hormones (estrogen, progesterone, testosterone, cortisone, DHEA) are much more reliable when tested for by this newer technology, using saliva rather than blood.

Even the NIH and World Health Organization have discovered and are now utilizing saliva testing for its ease, low cost, and superiority.


Regarding thyroid hormones, blood is a fine way to test for its levels in the body, but capillary blood by the new finger-stick technology (as opposed to the older "needle in an arm vein" technology) is a much more accurate measurement of your true thyroid status. You can even measure thyroid antibodies by this more sensitive method. Whether its Free T4, or Free T3, and especially with TSH, blood spot finger prick technology is definitely better.

For example, TSH tests are most often drawn in the morning at conventional laboratories. The blood often sits around in tubes all day long until run by some large machinery at a central lab far from the draw station, generally in the evening. More often, blood is drawn in your doctors' office or at a small satellite lab, then courier trucks come and pick up the samples and deliver them elsewhere. The point is that during all of this time, sometimes many hours, fragile TSH molecules are degrading in the tube as a liquid. This results in the test showing a lower TSH than you actually have, which means, ultimately, that you don't get diagnosed until much later than you should, and once diagnosed, you don't get as high a dose of thyroid medicine as you truly need.

Far better is the new technology of finger-prick blood spot testing. Several drops of blood from your finger are placed on a special filter paper. Once dry (within a few minutes) the level of TSH in that sample if fixed and solidly reliable for weeks! (It's only in a liquid form that TSH degrades rapidly).

Best of all, however, is that saliva testing and finger prick blood assay testing are now available without a doctor's prescription. You can order on-line at CanaryClub.org, a kit arrives in the mail to your home. You provide the samples, to the lab, at your convenience and  from the privacy and comfort of you own living space. Then, you simply send the kit back directly to the lab, in its prepaid mailer. Your results are mailed back to you within 7-10 days from the time the lab receives the results.  Check the Understanding Your results Section for additional information.
Finally, if you would like further interpretation about exactly what these results mean for your own personal health status, you can simply sign up for a personalized telephone coaching session with a seasoned physician hormone expert at: Canary Club.Org
