Feasibility and Validity of In-Home Self-Collected Capillary Blood Spot Screening for Type 1 Diabetes Risk.

Self-collection of a blood sample for autoantibody testing has potential to facilitate screening for type 1 diabetes risk. We sought to determine the feasibility and acceptability of this approach and the performance of downstream antibody assays. People living with type 1 diabetes and their family members ( = 97) provided paired capillary blood spot and serum samples collected, respectively, by themselves and a health worker.
