Glucose in Predialysis Urine (Mass Concentration)
This test measures the amount of glucose, a type of sugar, found in your urine before you start dialysis treatment. It helps monitor how well your body is handling glucose before kidney function support begins.

Why This Test Matters
Glucose in urine can indicate whether your body is breaking down food for energy properly. High levels may suggest diabetes or other metabolic conditions that require careful management before dialysis begins.
What to Expect During the Test
You’ll provide a urine sample (usually collected over a short period or a single sample) in a sterile container. The lab will test for glucose using a method that detects its presence without specifying exact concentration values.
Common Causes of Glucose in Urine
Glucose may appear in urine if your kidneys aren’t reabsorbing it properly, which can happen with diabetes, kidney disease, or other metabolic disorders. This test helps track how your body handles glucose before starting dialysis.
What This Test Can’t Tell You
This test doesn’t measure blood glucose levels or provide a full picture of your diabetes control. It focuses specifically on glucose in urine, which can be influenced by hydration, diet, or kidney function.
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.
High urine glucose levels before dialysis may signal poor metabolic control, requiring adjustments to diet, medications, or dialysis timing. Low or absent glucose could indicate normal glucose handling or kidney reabsorption function, but further evaluation may be needed.
