The use of glucose meters for point-of-care testing with critically ill patients is controversial.[1-4] Error sources are poorly understood. Nonetheless, handheld glucose meters are in widespread use in critical care settings. Few data are available for the latest generation of devices. Variations in [PO.sub.2], [PCO.sub.2]], pH, and some drugs used in critical care can affect glucose measurements.[5,6] The objectives of this study were (1) to determine hematocrit effects on glucose measurements obtained with the latest generation of handheld glucose meters; (2) to quantitate changes in glucose measurements observed with low, normal, and high hematocrit levels; and (3) to ...
