1-Hour Post-Load Glucose
- Sample Type
- Standard
- Fasting
- No
- Unit
- mg/dL
Part of the Glucose Tolerance Test (GTT), this measures the blood sugar level exactly 60 minutes after consuming a standardized glucose load (usually 75g or 100g). It evaluates the body's peak insulin response and its ability to manage a carbohydrate challenge. It is a critical metric for diagnosing Gestational Diabetes and identifying early-stage glucose intolerance.

Why Context Matters
Results are sensitive to the rate of gastric emptying and physical activity during the waiting hour. If the patient vomits the glucose solution or remains excessively active, the result may be falsely altered. Medications like steroids or diuretics also significantly impact the glucose curve.
Lab ranges are statistical averages, not biological laws. "Normal" for a 20-year-old male isn't normal for a 60-year-old female.
