Self assessment/CPD answers

Correct answer: A. As per American Diabetes Association guidelines, if a patient has discordant results on two different tests for diabetes, the test that has produced a result above the diagnostic cut-off point should be repeated, and the diagnosis made on the outcome. In this case, the fasting glucose is in the prediabetes range but the HbA1c is in the diabetes range. In this scenario the HbA1c should be repeated. An oral glucose tolerance test (C) and fasting glucose and insulin (D) are unnecessary.
