STUDY OBJECTIVE: Although reagent strips are commonly used, their reliability to estimate blood @entity413 concentration and guide administration of @entity413 solutions in the emergency department environment has not been proved. We determined the accuracy of visually interpreted reagent strips (Chemstrip bG, Boehringer Mannheim Corp, Indianapolis, IN) and their ability to identify hypoglycemic @entity1 in the @entity2613 . METHODS: We conducted a prospective, nonrandomized blinded clinical study of the visual estimation of blood @entity413 values by @entity2613 personnel using Chemstrip bG reagent strips during a 4-month period. Simultaneously obtained blood samples sent for laboratory @entity413 determination served as controls. The study was conducted at a large university hospital @entity2613 with an urban @entity1 population. A convenience sample of 215 adult @entity2613 patients underwent serum @entity413 determination with data form completion. No study intervention was tested, although timing of administration of @entity413 solutions, if given, was recorded. RESULTS: @entity4053 was defined as a @entity413 concentration less than 60 mg/dL on standard laboratory analysis. Reagent strips identified 28 of 29 of these @entity1 (sensitivity=97%), and 171 of 182 @entity1 without @entity4053 (specificity=94%, negative predictive value=99%) compared with control samples. The 1 false-negative reagent strip reading of 80 mg/dL was obtained from blood stored in a serum separator tube and had a laboratory @entity413 value of 39 mg/dL. Eighty-seven percent of the reagent strips were within +/-60 mg/dL of the control value for the laboratory @entity413 reference range less than 350 mg/dL. CONCLUSION: Visually interpreted Chemstrip bG reagent strips provide an acceptable estimation of blood @entity413 concentration in the @entity2613 and are highly sensitive in detecting @entity4053 .
