Combined Use of a Fasting Plasma Glucose Concentration and HbA1c or Fructosamine Predicts the Likelihood of Having Diabetes in High-Risk Subjects

Abstract

The paired values of FPG and HbA1c or FPG and fructosamine helped to identify potentially diabetic subjects, the diagnosis of which could be further confirmed by the 75-g OGTT. Using this approach approximately 80% of OGTTs could have been saved, depending on the diagnostic cutoff value of FPG.
