*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).

Recommended with chronic stress, fatigue, sleep disturbances, allergies and/or lowered immunity; indicator of adrenal imbalance. Tests adrenal hormones DHEA-S and diurnal cortisol (morning, noon, evening, nighttime). (Saliva Test)
