J Clin Endocrinol Metab
December 2012
Context: The T1D Exchange includes a clinic-based registry, a patient-centric web site called Glu, and a biobank.
Objective: The aim of the study was to describe the T1D Exchange clinic registry and provide an overview of participant characteristics.
Design: Data obtained through participant completion of a questionnaire and chart extraction include diabetes history, management, and monitoring; general health; lifestyle; family history; socioeconomic factors; medications; acute and chronic diabetic complications; other medical conditions; and laboratory results.
Background: The Afinion HbA1c (Axis-Shield) is a newer point-of-care device for measurement of hemoglobin A1c (A1C) using a boronate affinity method unlike the more commonly used DCA immunoassay method (Siemens Medical Solutions Diagnostics). The Afinion's accuracy and precision, when compared with high-performance liquid chromatography (HPLC) and DCA methods, have not been established in pediatric practice settings.
Methods: Capillary blood was collected from 700 subjects with diabetes mellitus at seven Pediatric Diabetes Consortium sites.
