The serum-based test was found to be positive in all 114 celiac patients, or 100% sensitivity, and among the controls which included three with celiac disease there was 94.9% sensitivity. The accuracy of the blood drop-based assay testing was positive in 46 of the 51 celiacs tested, which equals 90.2% sensitivity. The accuracy, however, is actually higher because five of the patients who tested negative had total IgA deficiency, so the real sensitivity level is actually 95.8%. All 100 controls tested negative which equals 100% specificity.
Given the high degree of accuracy of the two commercial test kits that were evaluated the researchers conclude that general practitioners should utilize these low cost kits during standard office visits whenever celiac disease is suspected.
