A Hospital System Glucose Meter That Produces Plasma-Equivalent Values from Capillary, Venous, and Arterial Blood

Abstract

The use of point-of-care meters for bedside blood glucose monitoring has become common in hospitalized patients. The management of patients in critical care units, those receiving aggressive supportive therapy, and those with type 1 or 2 diabetes may require frequent testing of their blood glucose concentrations (1)(2)(3). Bedside monitoring is often done with capillary whole blood from a fingerstick, and these whole-blood glucose meters produce values 8–10% lower than those in plasma (4). However, most clinical laboratory instruments measure glucose concentrations in plasma or serum, not whole blood. A whole-blood glucose meter that reports a plasma-equivalent result might be useful to reduce possible confusion when comparing glucose meter and laboratory glucose values. Here, we evaluated the SureStep®-Pro Hospital System, a reflectance meter that uses glucose oxidase chemistry to report plasma-equivalent glucose concentrations from capillary, venous, and arterial whole blood. We compared whole-blood and plasma glucose concentrations measured by the SureStep-Pro Hospital System (LifeScan) with values from the One Touch® II Hospital System (LifeScan), the Yellow Springs Instrument Model 2700 Select Biochemistry Analyzer (YSI), and the Vitros 750 Analyzer (Johnson & Johnson).
