2-Hour Post-Load Glucose
- Sample Type
- Standard
- Fasting
- No
- Unit
- mg/dL
This component is part of the Oral Glucose Tolerance Test (OGTT). It measures how effectively the body clears a standardized 75-gram glucose load from the bloodstream after two hours. It is considered more sensitive than fasting glucose for identifying Impaired Glucose Tolerance (IGT) and early-stage Type 2 Diabetes, as it specifically tests the insulin response to a carbohydrate challenge.

Why Context Matters
Results can be skewed by recent physical activity, acute illness, or certain medications like corticosteroids and thiazide diuretics. Inadequate carbohydrate intake (less than 150g/day) for the three days preceding the test can also lead to false-positive results for glucose intolerance.
Lab ranges are statistical averages, not biological laws. "Normal" for a 20-year-old male isn't normal for a 60-year-old female.
