In this episode of The Long Haul with Summer, we sit down with Mendel Fishman—entrepreneur, researcher, and long COVID patient—who is pioneering new diagnostic tools to transform how long COVID is identified and managed. Mendel shares his personal journey, the challenges of launching a biotech startup, and how innovative assays could help clinicians diagnose patients faster, more accurately, and with fewer financial burdens. We also discuss collaborations, upcoming clinical validations, and what he hopes policymakers, providers, and patients understand about the urgent need for long COVID research.Learn more about the Microvascular Research Foundation and how you can help at https://mvresearch.org/
