Researchers are studying blood samples from people with Long COVID who are experiencing depression, anxiety, and fatigue. They're looking at specific molecules called microRNAs and vitamin B12 levels to understand what changes happen in the body after COVID-19 infection and to find better ways to diagnose and treat Long COVID.
Right now, there's no reliable way to diagnose Long COVID, and doctors don't fully understand why some people develop depression, anxiety, and fatigue after COVID-19. This study aims to identify the biological changes that occur so doctors can create more targeted treatments and diagnostic tests.

If you join this study, you will donate a blood sample that researchers will analyze for microRNAs and vitamin B12 levels. You'll be compared with a control group of people who didn't have Long COVID symptoms. The study involves a single visit to provide your blood sample and basic health information.
