The Glucose – Post Prandial (PP) test is a blood test used to measure the blood sugar level after a meal. It is typically done two hours after a meal and helps determine how well the body is able to process glucose. The test is used to diagnose and monitor diabetes, a condition in which the body is unable to produce or effectively use insulin, a hormone that regulates blood sugar levels. A high postprandial glucose level may indicate that the body is not producing enough insulin or that the insulin it produces is not working effectively. This test is particularly useful for people who experience symptoms of high blood sugar after eating, such as fatigue, excessive thirst, or frequent urination. By monitoring postprandial glucose levels, doctors can make adjustments to a patient’s treatment plan to manage diabetes effectively and reduce the risk of long-term complications.
