Hey practitioners! 👋 Join Dr. Aristo Vojdani, PhD, MSc, CLS, for an insightful webinar, "Beyond Exposure: Understanding Immune Reactivity Patterns," on Thursday, August 7 at 12:00 PM EST / 9:00 AM PT.

In this session, you’ll explore how immune reactivity testing may provide additional insights into how the body responds to environmental compounds, food additives, and microbial byproducts. Dr. Vojdani will walk through key Cyrex panels that offer complementary perspectives to traditional exposure assessments, supporting clinicians in recognizing immune response patterns that may inform personalized wellness and functional care strategies.
