In plain language

What this test helps you understand

Assesses postprandial glucose metabolism 20 hours after a meal, aiding in the diagnosis and management of diabetes mellitus.
The Glucose 20 Hour Post Lunch Test measures your blood glucose levels 20 hours after eating a meal. This test is important for people at risk of diabetes or those already diagnosed with the condition. It helps assess how your body processes glucose after a meal, aiding in effective diabetes management and the prevention of potential complications.

This test specifically measures the glucose concentration in your blood at the 20-hour mark post-meal. We utilize the Hexokinase method, known for its accuracy in measuring blood sugar.

Consider this test if you are experiencing symptoms like excessive thirst, frequent urination, or fatigue, have a family history of diabetes, are overweight, or lead a sedentary lifestyle. It is also recommended for individuals already diagnosed with diabetes who require ongoing monitoring of their condition.

Benefits include early detection of diabetes or prediabetes, improved management of existing diabetes by understanding your body's response to food, guidance for necessary lifestyle and dietary changes, and reassurance through effective blood glucose monitoring.

Your results will show your blood glucose level 20 hours after your meal. Discuss these results with your doctor to understand their implications for your health and diabetes management plan.
