Why This Test Is Done
Your doctor may order this test if you have symptoms of diabetes, such as frequent urination, excessive thirst, or unexplained weight changes. It may also be used to evaluate how your body handles glucose after eating, especially if you have risk factors like obesity, a family history of diabetes, or high blood pressure.
What to Expect Before the Test
You’ll follow a specific diet and drink schedule before this test. Typically, you’ll eat a standard meal and then drink a sugary liquid. Your urine will be collected at set intervals (including 2 hours post-meal) to measure glucose levels.
What Happens During the Test
No special preparation involves drawing blood—this test specifically measures glucose in your urine. You may collect urine samples at home or in a clinic, depending on instructions. The test checks for glucose in your urine after eating.
What the Results Mean
Higher than expected glucose in urine after eating may indicate poor glucose control, which can be linked to diabetes or insulin resistance. Your doctor will interpret results in relation to your overall health and medical history.
