Researchers are trying to find biological markers — measurable signs in your blood, saliva, stool, or tissue — that can help diagnose Long COVID. Right now, there's no specific test to confirm Long COVID, which makes it hard for doctors to diagnose the condition and develop treatments. This study will collect samples from people with Long COVID and people who recovered from COVID infection, and share them with research labs working to develop reliable diagnostic tests.
Long COVID affects millions of people, but without a reliable biological test, doctors struggle to diagnose it and researchers can't develop effective treatments. This study creates a central resource of carefully collected samples to help multiple research labs work together on developing better diagnostic tests.

You will provide non-invasive samples including blood, saliva, and stool, and may also be asked to undergo a tissue biopsy (a small sample of tissue taken with a needle or small surgical procedure). These samples will be sent to research laboratories across the country, where scientists will study them to identify biological markers that can help diagnose Long COVID. The study is part of a larger research program, so you'll likely have visits over time as researchers track changes in your condition.
