Researchers want to understand why people with long COVID often feel exhausted and weak. This study will measure how well the energy-producing structures inside your cells are working by testing your blood, skin, and muscle. By comparing these measurements between people with long COVID and those who fully recovered, the research team hopes to find a pattern that could help diagnose and treat long COVID.
Many people with long COVID describe severe fatigue and reduced ability to exercise, but doctors don't yet have clear ways to measure what's going wrong at the cellular level. This research aims to fill that gap by developing reliable tests that could one day help diagnose long COVID and guide treatment.

You would visit the hospital twice over about a week. During these visits, you'll complete some surveys, wear an activity tracker for 7 days, undergo simple non-invasive tests (like measuring oxygen use in your skin and blood), and donate a blood sample. All the tests are designed to be safe and straightforward — there are no medications to take or invasive procedures involved.
