Point-of-Care Hemoglobin A1c

Abstract
A 57-year-old white man with obesity and hypertension presents for a primary care visit, during which he expresses concern about having diabetes. He reports no symptoms of hyperglycemia, such as frequent urination, increased thirst, fatigue, or visual changes, and had no known family history of diabetes. A series of blood tests had recently been obtained (Table). His body mass index (BMI) is 33.9 and his blood pressure is 160/90 mm Hg. The patient wants to know if a test could be done in the office to determine if he has diabetes.
