Objective To compare characteristics of autoantibody ( aAb )‐positive and ‐negative cases of type 1 diabetes ( T1D ) <18 years old in the T1D Exchange clinic registry. Methods An aAb ‐positive status ( n = 6239) required at least one of the aAbs to be positive; an aAb ‐negative status ( n = 485) required negative results on testing of at least two different aAbs . Results The percentage of males was higher (58% vs 51%; P = 0.002) and total daily insulin dose lower ( P = 0.003) in aAb ‐negative compared with aAb ‐positive groups, but both groups had similar distributions of race–ethnicity, diagnosis age, family history of T1D , ketoacidosis at diagnosis, body mass index at diagnosis and at most recent office visit, and current HbA1c . Conclusions Male gender and lower total daily insulin dose were more likely in aAb ‐negative than aAb ‐positive children with T1D , but no other distinguishing characteristics were identified. Further examination of characteristics of aAb ‐negative cases may help characterize the heterogeneous nature of T1D .
