About this test

What is a Fasting and Post‑Prandial Glucose Test?

The test measures the amount of glucose (sugar) in your blood at two points: after an overnight fast and 2 hours after a meal. It helps evaluate how well your body regulates blood sugar.

Key Parameters

ParameterWhat it shows
Fasting Plasma Glucose (FPG)Blood sugar level after 8‑12 hours of fasting
Post‑Prandial Glucose (PPG)Blood sugar level 2 hours after a standard meal

Why It Is Done

  • Routine health check‑ups
  • Evaluation of symptoms such as frequent urination, thirst, or unexplained weight loss
  • Monitoring of known diabetes or pre‑diabetes
  • Screening for gestational diabetes in pregnant women

Early Detection

This test can help identify signs of Type 2 Diabetes, Prediabetes, and Gestational Diabetes, but it does not diagnose on its own. A doctor interprets the result together with symptoms, history, and other tests.

What Abnormal Results May Indicate

  • High fasting glucose may suggest impaired fasting glucose or diabetes.
  • High post‑prandial glucose may indicate impaired glucose tolerance or diabetes.
  • Low glucose can be due to hypoglycemia, certain medications, or other conditions.

Many factors—hydration, recent meals, stress, medications—can affect results.

Who Should Consider This Test

  • Adults over 45 years old
  • Individuals with risk factors such as obesity, family history of diabetes, or hypertension
  • Pregnant women in the second or third trimester
  • People experiencing symptoms of high or low blood sugar

Quick Takeaway

Fasting and post‑prandial glucose tests are simple blood tests that help detect and monitor blood sugar abnormalities, guiding appropriate medical care.

Before your test

Preparation

  • Fasting: Do not eat or drink anything except water for 8‑12 hours before the fasting sample.
  • Post‑prandial: After the fasting draw, eat a standard meal (usually 75 g of carbohydrates) and wait 2 hours before the second sample.
  • Combined tests: If you are also having tests that require fasting, follow the longest fasting period (usually 8‑12 h).
  • Procedure: A healthcare professional will draw blood from a vein in your arm using a small needle. The whole process takes about 5–10 minutes.
  • Expectations: You may feel a brief pinch or sting when the needle is inserted. Blood flow is usually painless.
  • Precautions: Stay hydrated, avoid alcohol and strenuous exercise 24 hours before the test, and inform the staff of any medications you are taking.
  • Final note: Confirm specific preparation details with your doctor or the lab. This information is general educational guidance and not a substitute for professional medical advice.

Report parameter guide

Fasting Glucose

Blood sugar level after an overnight fast

Low: May indicate low blood sugar (hypoglycemia) due to factors such as excessive insulin, certain medications, or hormonal imbalances

High: May indicate high blood sugar (hyperglycemia) suggestive of impaired glucose tolerance or diabetes

Post Prandial Glucose

Blood sugar level measured 2 hours after a meal

Low: May indicate low blood sugar after eating, possibly due to excess insulin or certain medications

High: May indicate high blood sugar after eating, suggestive of impaired glucose tolerance or diabetes
