Both kits include the same 26-marker urinary neurotransmitter profile. Learn what four saliva cortisol measurements add, how sample collection differs, and what to discuss with your healthcare professional before choosing a panel.

ZRT offers a unique approach to neurotransmitter testing, analyzing 14 key neurotransmitters and metabolites to provide a comprehensive view of your neurochemistry. Unlike other labs, ZRT combines parent neurotransmitter levels with their downstream metabolites, ensuring accurate results and more effective treatment plans. This comprehensive testing, available exclusively through ZRT, helps identify systemic patterns that may be contributing to your health issues.

Neurotransmitter imbalances are often linked to common conditions like anxiety, depression, ADHD, and PMS. ZRT’s testing also examines the influence of hormones, heavy metals, and nutritional elements, offering a more complete and precise understanding of your health.

For the most accurate and convenient testing, ZRT's dried urine method allows for discreet, at-home collection—no need for all-day urine collection. The dried strips are easy to mail back, providing a hassle-free way to assess your neurotransmitter levels.
