INS and type 1 diabetes mellitus: It is noteworthy that one group reported good concordance between insulin antibody titers using dried capillary blood spots and serum; however, only 15 T1D subjects in their cohort were positive for insulin antibodies.[22] Our results need to be validated in a larger cohort of patients using a capillary finger-stick to obtain DBS followed by a confirmatory serum test on patients with positive iAb before DBS methodology can be widely adopted as a screening test.
