Prediabetes Lab Tests - Explained
Prediabetes can be diagnosed by the following tests:
- Glycosylated hemoglobin/Hemoglobin A1C Test (A1C)
- Fasting Plasma Glucose Test (FPG)
- Oral Glucose Tolerance Test (OGTT)
Hemoglobin A1C shows the average blood glucose level over a period of approximately three months. Patients are not required to fast or drink solutions prior to this test.
Fasting Plasma Glucose measures blood glucose levels while having nothing to eat or drink (hence "fasting") over a period of at least eight hours.
Oral Glucose Tolerance Test measures blood glucose levels at baseline and again two hours after drinking a sweetened solution,
If you have questions regarding your lab tests or your diagnosis, don't be afraid to ask your medical provider about your results. Your provider can further explain your results and the numbers associated with the lab results.
