Fasting Plasma Glucose Interpretive Guidelines (8-16 hours fasting):
Fasting Plasma Glucose Reference Range 70-99 mg/dL
Impaired Fasting Glucose Reference Range 100-125 mg/dL
Provisional Diagnosis of Diabetes Mellitus* ≥ 126 mg/dL
Random Plasma Glucose Interpretive Guidelines (<8 hours fasting):
Random Plasma Glucose Reference Range 70-130 mg/dL
Positive Random Plasma Glucose Screen* ≥ 160 mg/dL
Provisional Diagnosis of Diabetes Mellitus* ≥ 200 mg/dL and symptoms of DM
*Diagnosis of diabetes mellitus (DM) requires repeat testing (fasting glucose or 2 hour OGTT) on another day. Fasting is defined as no caloric intake for at least 8 hours but not longer than 16 hours.
