Dried Blood Spot Test for Glycated Hemoglobin Measurement in Pediatric Diabetes Care.

Background: The dried blood spot (DBS) card is a novel collection method for measuring glycated hemoglobin (A1C) in individuals with diabetes mellitus. The potential benefits of DBS specimens compared with traditional phlebotomy include a reduction in required total blood volume, reduced procedural pain, and an ability for self-initiated collection. DBS cards for A1C measurement have been validated in the adult population, but there is a paucity of pediatric data.
