Summary

This study is for people with Long COVID, Lyme disease, or ME/CFS (chronic fatigue syndrome). Researchers want to see if a special blood test can find problems with T-cells, which are part of the immune system. Participants will give blood samples and fill out symptom questionnaires at the start and after 6 months. No treatments are given—this is just to learn more about these conditions.
