2-Hour Postprandial Blood Glucose Test (2HPPG)

The 2-Hour Postprandial Glucose Test at Pamel Laboratories measures your blood sugar level exactly 2 hours after eating a meal. This test helps evaluate how well your body manages glucose after food intake and is particularly useful for diagnosing or monitoring diabetes mellitus, impaired glucose tolerance, and post-meal blood sugar control.

It is often used alongside fasting blood glucose or HbA1c tests for a more complete picture of glucose metabolism.

What the Test Measures:

• The level of glucose in your blood 2 hours after eating

• Helps determine your body’s insulin response and ability to regulate sugar levels post-meal

Purpose of the Test:

• Detect:

  • Type 2 diabetes

  • Pre-diabetes

  • Postprandial hyperglycemia

• Monitor glucose control in known diabetics

• Evaluate symptoms like:

  • Fatigue after meals

  • Blurry vision

  • Unusual thirst or urination

• Often used during pregnancy screenings for gestational diabetes

Sample Type: Blood sample (serum or plasma)
Preparation: Eat a normal meal, then have your blood drawn exactly 2 hours after your first bite
Turnaround Time: Same day (within a few hours)

Interpretation Guide:

• Normal: <140 mg/dL (7.8 mmol/L)

• Impaired glucose tolerance (Pre-diabetes): 140–199 mg/dL (7.8–11.0 mmol/L)

• Diabetes: ≥200 mg/dL (≥11.1 mmol/L)
