Neurotransmitters are chemical messengers that transmit signals between nerve cells in the nervous system. A balanced level of these neurotransmitters is essential for overall health. When imbalanced, they can cause neurological or psychological issues, such as anxiety, depression, chronic fatigue, or insomnia.

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.

In their conversation, McAvoy and Dr. Zava discuss his early research, the development of non-invasive hormone testing through saliva, and how this has revolutionized how clinicians understand hormone health. Dr. Zava also touches on his significant findings regarding the metabolism of estrogen and how lifestyle factors can influence cancer risk. He reflects on the challenges he faced in the early days of ZRT Laboratory, including financial struggles, but also shares the satisfaction of making a real difference in the lives of patients and healthcare providers.

For McAvoy, Dr. Zava’s work has been instrumental in shaping his own approach to patient care. ZRT's comprehensive hormone testing, including their Hormone Profile III, has helped countless practitioners like McAvoy identify hormonal imbalances and tailor treatments that improve patient well-being.
