Cortisol is the stress hormone produced in the adrenals. It runs on a circadian rhythm. Therefore, to get a true picture of your cortisol "rhythm", it is best to test 2-4 times throughout the day. Using a saliva test kit is the most efficient and accurate way to do this.

Saliva testing measures the bioavailable amount of hormone available to target tissues. For this reason, saliva testing better relates to specific symptoms of excess or deficiency, and is a good option for monitoring hormone therapy. A simple blood spot test is also offered and can provide a helpful picture of hormone amounts in the body. A dried urine test is available for heavy metal testing.

It is easy to do during a typical day in your life at home or at work. No need to go to a lab! 

Unlike other labs, ZRT laboratory adjusts hormone ranges based on age, menstrual status, and supplementation types. This is the ideal method for tracking the effectiveness of hormone treatments and identifying your needs. You do not need to stop your current supplement regimen to support hormones to do this test. 

ZRT is the only lab to perform an extraction process for saliva testing, which separates hormones from background contamination, making for more accurate saliva testing.

Heavy metal exposure is on the rise. Common sources include cigarettes, seafood, rice, well water & dental fillings. A simple at-home heavy metal test can help identify one of the root causes of imbalance in the body and direct the appropriate course of action for treatment. 

ZRT laboratory takes your symptoms, supplements, medications, age, and menstrual status into consideration when providing your results. You will get a comprehensive and detailed report of what your levels are and what they mean. After your results are in, you will have the opportunity to set up a consultation with a functional medicine dietitian (for a discounted rate) where a specific plan of action will be provided based on your results and your health goals.
