  1. Number of serum samples are given with and percentages in parentheses. Samples positive for EMA were tested in serial dilutions (1 in 30, 1 in 100, 1 in 300 and 1 in 1000). Anti tTG antibody results are reported as positive (OD ratio >1.4), borderline (OD ratio 1–1.4) and negative (OD ratio <1).
