title: Discrepant Glucose Results between Capillary and Venous Blood in an 83-Year-Old White Man.
abstract: Herein, we present a case of pseudohypoglycemia induced by hypothermia in an 83-year-old white man in whom glucose levels between venous and capillary blood were discrepant. Although pseudohypoglycemia has been reported in the literature, it is under-recognized among health care professionals and laboratorians. Health care professionals may encounter pseudohypoglycemia using glucose meters; the potentially inaccuracy of glucose meter results for critically ill patients has been intensely debated recently. Thus, this article should be educational for the point-of-care community.
