The PPBS (Postprandial Blood Sugar) test is a diagnostic tool used to measure a person's blood sugar level after a meal. It is typically performed two hours after consuming a meal to assess how well the body is able to regulate blood glucose levels. This test is commonly used to diagnose and monitor diabetes. By measuring the rise and fall of blood sugar levels after eating, healthcare professionals can evaluate a person's glucose metabolism and determine if their body is effectively processing and utilizing glucose. The PPBS test helps in understanding how food intake affects blood sugar levels, enabling healthcare providers to make informed decisions regarding dietary modifications and medication adjustments. It plays a crucial role in managing diabetes and preventing complications associated with high blood sugar levels.
