Spit test could replace needles for tetanus check
NCT ID NCT07446166
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study aims to create a quick, non-invasive test using saliva to see if someone has enough antibodies to fight tetanus. Instead of drawing blood, a small saliva sample on a test strip would give results in 10-15 minutes. The test is designed for low- and middle-income areas where lab access is limited, helping people know if they need a vaccine booster. About 390 healthy volunteers, including children, adults, and pregnant women, will take part to see how well the saliva test matches standard blood tests.
