Use of high‐normal levels of haemoglobin A1C and fasting plasma glucose for diabetes screening and for prediction: a meta‐analysis

Using high‐normal levels of haemoglobin A1C (Abnormal‐A1C) or fasting plasma glucose (FPG) (Abnormal‐FPG) for diabetes screening are expected to improve the ability to detect persons with or at high risk of diabetes. We assessed the diagnostic and predictive capacity for diabetes of Abnormal‐A1C and Abnormal‐FPG. We compared these to the combined use of the two measures to the single use of either measurement.
