The Blood Sugar Post Prandial Test The Blood Sugar Post Prandial test, also known as the Postprandial Blood Glucose (PBG) test, is used to measure the level of glucose (sugar) in the blood after an individual has eaten a meal. It is used to monitor glucose levels in individuals with diabetes and to help evaluate how well a diabetic treatment plan is working. Pre-test preparation:The individual should eat a meal before the test. The test is usually performed 1-2 hours after the start of a meal. Testing method:A small sample of blood is taken from a finger prick or from a vein and sent to a laboratory for analysis. Common symptoms that may prompt a healthcare provider to prescribe a blood sugar post prandial test include: Increased thirst and urination Fatigue Blurred vision Slow wound healing Tingling or numbness in the hands or feet Diagnosis:High levels of glucose in the blood after a meal can indicate uncontrolled diabetes or prediabetes. Reference range:Normal values for blood sugar levels in the blood vary depending on the laboratory, but generally range from less than 140 milligrams per deciliter (mg/dL) for postprandial blood glucose.It’s important to note that the test results should be interpreted in the context of the patient’s clinical presentation and other test results. A single test result should not be used as the sole basis for diagnosis and treatment decisions. A qualified healthcare professional should interpret the test results and give you a proper diagnosis. Additionally, other tests like the fasting blood sugar and Hemoglobin A1c test, urine routine test can also be used to diagnose diabetes and monitor glucose control over time.
