*PLEASE NOTE: Residents in California, Maryland, and New York must receive a signature from a licensed care provider in their state before ordering tests. Patients will need a laboratory order from a healthcare provider requesting the tests that they purchased – this is usually a script that looks similar to a prescription fill. It should contain the provider’s name, signature, contact information, and the ZRT tests ordered. This will be returned with the blood/urine/saliva sample(s).

Essential elements are only healthy when within optimal ranges. Levels too low or high can negatively impact our health, so it's important to know if our levels are outside the ideal range.

Tests in this urine profile are Iodine, Selenium, Bromine, Lithium, Arsenic, Cadmium, Mercury & Creatinine.
