title: Effect of hematocrit concentration on blood glucose value determined on Glucometer II.
abstract: Nineteen patient blood samples each with modified hematocrit concentrations of approximately 20, 30, 40, 50, and 60%, were assayed for their glucose concentration by the Glucometer II. Blood removal from the test strip was by the one- and two-blot techniques. The reference method was the Yellow Springs Instruments (YSI) blood glucose analyzer. Glucometer II results were falsely high for the single blot (13-59%, mean 33%) and double blot (12-41%, mean 19%) at 20% hematocrit and falsely low at 60% hematocrit for the single blot (22-44%, mean 37%) and the double blot (26-49%, mean 43%). At 40-50% hematocrit, Glucometer II and YSI results agreed only for the one-blot technique.
