Question #844

Which of the following is the correct diagnostic cut-point for diabetes?

 

Correct

Answer: C: 2-hour plasma glucose greater than or equal to 200 mg/dL during an oral glucose tolerance test

Educational Critique:  Patients who meet one or more of the following criteria meet the diagnostic cut-point for type 2 diabetes:

  • A1C = 6.5%
  • Fasting plasma glucose (FPG) = 126 mg/dL
  • 2-hour plasma glucose = 200 mg/dL during an oral glucose tolerance test
  • Random plasma glucose = 200mg/dL in a patient with classic symptoms of hyperglycemia or hyperglycemic crisis.

The diagnostic test results should be confirmed by a repeat test, unless clinical picture clearly supports the diagnosis.  Diabetes Care Jan.2016
