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.
