These 2 conditions rarely occur together, so when pseudohypoglycemia is suspected in one type of blood sample, measuring glucose concentration in the other type of blood sample usually makes the diagnosis.Objective: To describe a case of pseudohypoglycemia in both venous and finger-stick blood in a patient with the Eisenmenger syndrome.Case Report: A 44-year-old white woman with known Eisenmenger syndrome due to a large ventricular septal defect was hospitalized for an exacerbation of exertional dyspnea. ...References1.
