Retrospective Analysis of Point-of-Care and Laboratory-Based Hemoglobin A1c Testing

Glycemic control is essential to diabetic management, and hemoglobin A1c (Hb A1c) has long been used for this purpose. Though laboratory-based testing is standard, point-of-care (POC) systems provide rapid results in clinic, allowing more timely patient management. A negative bias with POC testing h...

Summary:Glycemic control is essential to diabetic management, and hemoglobin A1c (Hb A1c) has long been used for this purpose. Though laboratory-based testing is standard, point-of-care (POC) systems provide rapid results in clinic, allowing more timely patient management. A negative bias with POC testing has been observed, and our aim is to further characterize these discrepancies at our institution. A medical record search identified patients who underwent laboratory-based and/or POC Hb A1c testing (DCA Vantage™) at our medical center from July 2015 to April 2016. Patients who underwent both tests within 30 days were grouped by age, sex, and test interval (same day,
