NCT ID NCT04562285
First seen Jun 24, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This completed study looked at how well two different blood tests could detect antibodies against the virus that causes COVID-19. Researchers followed 829 adults who had tested positive for COVID-19, checking their blood during hospitalization and for up to 12 months afterward. The goal was to understand how long the immune response lasts and how accurately these tests measure it.
