Glucose, 24-Hour Urinary Total
This test measures the total amount of glucose (sugar) excreted in your urine over a 24-hour period. It helps assess how well your body is handling glucose, which can be important for managing conditions like diabetes.
["Helps track how much sugar your body removes through urine, useful for diabetes management."]

Why This Test Is Done
Your doctor may order this test to evaluate how your kidneys and body are processing glucose. It can help diagnose or monitor conditions like diabetes, kidney function, or metabolic disorders. It’s also useful in cases where you have unexplained high blood sugar levels or symptoms like frequent urination.
How the Test Works
You’ll collect all urine for a full 24-hour period in a special container. The urine is then sent to a lab, where it’s analyzed to measure the total glucose content. This test provides a broader picture of your glucose handling compared to a single blood or urine sample.
Sample Collection
To prepare, start collecting urine immediately after waking up and continue until you’ve collected urine for the next 24 hours. Empty your bladder before starting, then use the container provided to collect all urine throughout the day. Keep the container refrigerated if needed, but avoid freezing.
What to Expect
There are no special preparations needed beyond collecting urine over 24 hours. If you’re unsure about the timing or need help with the collection process, ask your healthcare provider for guidance. Some medications or foods can affect results, so let your doctor know if you’re taking any.
Reference range
Fasting: 70-100 mg/dLN/A
Fasting for 8-12 hours required. Water is permitted. Avoid chewing gum and smoking before the test.
Clinical interpretation
How abnormal results are interpreted and what conditions they suggest.
Elevated urinary glucose levels may indicate diabetes, kidney issues, or other metabolic problems. High levels can also signal poor control of blood sugar. Low levels might suggest dehydration or other conditions affecting glucose metabolism. This test helps monitor long-term glucose handling and can guide treatment decisions.
