Validation of a rapid test for celiac disease detection in first-degree relatives - A prospective study

Celiac disease (CD) is an autoimmune disorder triggered by gluten in genetically predisposed individuals, often diagnosed by detecting anti-tTG2 antibodies. First-degree relatives of CD patients are at high risk and require careful evaluation. We conducted a prospective study to validate CeliacDetect, a rapid immunochromatographic test that detects anti-tTG2 IgA antibodies in capillary blood within 10 minutes. Involving 95 first-degree relatives, the study showed that CeliacDetect had 100% sensitivity, specificity, positive predictive value, and negative predictive value. These results suggest CeliacDetect is a highly accurate, non-invasive screening tool for early CD detection.
