Urine Glucose - Postprandial

Urine Glucose – Postprandial is a diagnostic test used to detect the presence of glucose (sugar) in urine after food intake. Normally, glucose is not found in urine, as it is reabsorbed by the kidneys.

After a meal, blood sugar levels rise. If they exceed the kidney’s threshold, excess glucose is excreted in urine. This test helps evaluate how well the body manages glucose after eating and is useful in screening and monitoring diabetes mellitus.

A urine sample is collected after a meal (usually 2 hours post-meal) and tested for glucose. The presence of glucose indicates elevated blood sugar levels beyond normal limits.

The purpose of this test is to:

• Detect glucose in urine after meals
• Evaluate postprandial blood sugar control
• Screen for diabetes mellitus
• Monitor effectiveness of diabetes management
• Identify abnormal glucose excretion
