Glucose in Serum (24-Hour Urine Collection)
This test measures the amount of glucose (sugar) excreted in your urine over a 24-hour period. It helps assess how well your body is managing glucose levels, especially if you have diabetes or other conditions affecting sugar metabolism.
["This test helps track how your body handles sugar over time and may indicate diabetes or other metabolic issues."]

Why This Test Is Done
Your doctor may order a 24-hour urine glucose test if they suspect diabetes, prediabetes, or other conditions like kidney disease, gestational diabetes, or unexplained weight changes. It can also be used to monitor long-term glucose control in people with diabetes.
How the Test Works
You’ll collect all urine for a full 24-hour period in a special container. The test measures the total glucose lost in your urine, which reflects how much sugar your body isn’t reabsorbing back into your bloodstream.
Sample Collection
You’ll start by emptying your bladder into the container at the beginning of the 24-hour period (e.g., midnight). After that, you’ll collect every drop of urine for the next 24 hours, including during sleep. Store the sample in a cool place until you return it to the lab.
What to Expect
No special preparation is needed, but avoid taking diuretics (like caffeine or some medications) that could affect urine volume. Drink fluids normally unless instructed otherwise.
Reference range
Adult males: 8-61 U/L; Adult females: 5-36 U/LN/A
No special preparation required. Avoid fatty meals before the test if possible.
Clinical interpretation
How abnormal results are interpreted and what conditions they suggest.
High urine glucose levels may indicate diabetes, where the body struggles to regulate blood sugar. It can also signal kidney issues or other metabolic disorders. Low levels might suggest the body is absorbing glucose efficiently, but this is less common in routine testing.
