It’s a known fact that very high or very low glucose (blood sugar) levels are harmful to our body. Glucose is the main source of energy in our body and the hormone insulin helps the glucose to be used by the body’s cells correctly. Any imbalance of insulin also leads to imbalance of glucose in our body. High glucose level (Hyperglycemia) affects the organs of our body and low glucose level (Hypoglycemia) leads to brain and nerve malfunction. Postprandial urine glucose test measures the glucose level after having a meal or eating. 2 hours after eating, urine sample for testing postprandial glucose level is taken. The kidney filters the blood to form urine. Normally, urine has little or no glucose. In case of very high glucose level, glycosuria or high level of glucose in the urine is noted. The test results help to monitor insulin therapy in patients with diabetes mellitus.
