Effects of pH on Glucose Measurements With Handheld Glucose Meters and a Portable Glucose Analyzer for Point-of-Care Testing

Abstract

Because of potential risk in diabetic patients with ketoacidosis and in other patients with acid-base disorders, we recommend that clinicians choose glucose devices carefully and interpret the measurements cautiously when point-of-care glucose testing is performed in critically ill patients with acidemia, alkalemia, or changing acid-base status.
