Why is oral glucose tolerance test not suitable for diagnosing hypoglycemia?

When should an OGTT not be performed?
1 An OGTT is unnecessary if fasting or random blood glucose values are clearly in the nondiabetic or diabetic range: fasting or random <5.5; fasting ≥7.0 or random ≥11.1 mmol/L respectively. Diagnosis should be based on laboratory results, not results from a benchtop glucose meter.
