Advancements in Blood Testing for Long COVID Detection and Treatment

A groundbreaking study led by researchers from the Icahn School of Medicine at Mount Sinai and Yale School of Medicine has identified distinctive blood biomarkers in long COVID patients, establishing clear differences in immune and hormone function compared to individuals without the condition. Key biomarkers include abnormal T cell activity, reactivation of latent viruses like Epstein-Barr, and reduced cortisol levels. This discovery paves the way for more personalized testing and treatments for long COVID, providing a scientific rationale for the persistent symptoms experienced by these patients.
