Home Testing

 We recommend using the ZRT Lab’s new technology of saliva and blood spot testing, which is superior in our view to standard blood draw tests for thyroid and other hormones.  To assist you in securing this high-quality home testing at the lowest possible cost, we recommend ordering your ZRT testing through The Canary Club, a health and wellness advocacy group that we helped create. For those interested in reviewing research on the increased accuracy and effectiveness of this newer technology, you may visit our Validity of Saliva Testing page.
