2-Hour Post-Prandial Blood Sugar (PPBS)
- Sample Type
- Standard
- Fasting
- No
- Unit
- mg/dL
The 2-Hour Post-Prandial Blood Sugar (PPBS) test measures the body's ability to metabolize glucose following a meal. Specifically, it assesses the effectiveness of the insulin response in clearing glucose from the bloodstream. In a healthy individual, insulin levels spike after eating to transport glucose into cells, returning blood sugar to near-baseline levels within two hours. This component is critical within the FBS & PPBS panel to diagnose Impaired Glucose Tolerance (IGT) and monitor the management of Type 1 and Type 2 Diabetes Mellitus. It provides a more dynamic view of metabolic health than a Fasting Blood Sugar (FBS) alone.

Why Context Matters
Results can be significantly skewed by the carbohydrate content of the meal consumed, the timing of the blood draw (exactly 120 minutes is required), physical activity immediately following the meal, and medications like corticosteroids or beta-blockers.
Lab ranges are statistical averages, not biological laws. "Normal" for a 20-year-old male isn't normal for a 60-year-old female.
