Karen Schroeder Kassel, MS, RD, MEd Finding diabetes can help to decrease complications. It may also find a condition called prediabetes. This is a blood glucose level that is high but not yet diabetes. It will often move on to type 2 diabetes. Finding it early may help to prevent diabetes from starting. Screening tests are given to people who may be at high risk. Screening GuidelinesAmerican Diabetes Association (ADA) recommends screening for prediabetes and type 2 diabetes in the following:
Screening may be repeated again in 3 years. Screening TestsHbA1c TestThe HbA1c test is a good indicator of your average blood glucose levels over the past 2-4 months. This test usually does not require any dietary restrictions.
Fasting Plasma GlucoseWith this blood test, you need to fast (not eat anything) for at least 8 hours before the test.
Two-Hour Oral Glucose Tolerance TestAfter fasting overnight, the doctor tests your glucose level. You are then asked to drink 75 grams of glucose dissolved in water. Two hours later, the doctor tests your glucose level again.
