Tata Projects Glucose PP also known as PPBS (Postprandial Blood Sugar) test, measures the blood glucose (sugar) level after a meal, typically two hours after eating. It is often done as part of routine health checkups and when one experiences symptoms of altered blood sugar levels. This test measures how well your body can handle glucose after eating. It may be performed along with a fasting blood glucose test. This test helps assess the risk for diabetes and check the effectiveness of the ongoing medication. Early detection and treatment of diabetes are important to prevent complications such as heart disease, kidney damage, and nerve damage.
