Methods: In this prospective cohort study, waste blood samples from residents of a community were tested for CeD autoimmunity at 2 time points. We analyzed waste blood samples from 15,551 adults for tTGA and, if titer results were above 2 U/mL, for endomysial antibody. The median interval between the two time points was 8.8 years.

Results:

  • Of the serum samples collected at the first time point, 15,398 had negative results for tTGA, and 153 had positive results for tTGA (>4 U/mL). Based on medical records, 6 individuals received a diagnosis of celiac disease, for a cumulative incidence of celiac disease diagnosis of 0.06% over 10 years.
  • Forty-nine (0.32%) individuals with a negative result from the first serologic test for tTGA had a positive result from the second test
  • Among the 153 adults who were tTGA positive at the first time point, 31 (20%) had a subsequent diagnosis of celiac disease, 81 (53%) remained positive for tTGA without a clinical diagnosis of celiac disease, and 41 (27%) had negative test results for tTGA at the second time point.
