The Post Prandial Blood Sugar (PPBS) test measures your blood sugar level two hours after you eat a meal. This helps assess how your body processes glucose, a type of sugar that's your body's main energy source. Normally, your body releases insulin after eating to usher glucose from the blood into your cells. The PPBS test checks if your body is effectively managing this process. Doctors use this test to diagnose diabetes, and prediabetes and monitor blood sugar control in people already diagnosed with diabetes.
Reasons for Undergoing the Post Prandial Blood Sugar (PPBS) Test
The Post Prandial Blood Sugar (PPBS) test is a crucial diagnostic tool for various health-related purposes. Here are the main reasons for undergoing a PPBS test:
- Diagnosing and managing diabetes, especially in assessing blood sugar regulation after meals
- Screening for gestational diabetes during pregnancy, typically between weeks 24-28
- Evaluating insulin resistance and glucose tolerance, which are risk factors for diabetes and cardiovascular disease
- Assessing overall metabolic health and tailoring carbohydrate intake accordingly
- Monitoring the effectiveness of lifestyle changes, nutrition, exercise, or medication on blood sugar levels
List of Parameters Considered During the Post Prandial Blood Sugar (PPBS) Test
The post prandial blood sugar or PPBS test primarily focuses on measuring specific parameters related to glucose levels and metabolism. The main parameters considered during a PP sugar test include:
- Glucose Concentration: Measures the amount of glucose in the blood plasma 2 hours after consuming a meal, with normal levels typically not exceeding 140 mg/dL
- Peak Values: Assesses the peak glucose value, which usually occurs 2 hours after the start of a meal, providing insight into postprandial hyperglycemia
- Insulin and Glucagon Secretion: Indirectly reflects the body's response to carbohydrate absorption and its effect on glucose metabolism in the liver and peripheral tissues
