What Does This Test Measure?
Your blood glucose (sugar) level in serum or plasma. This is a standard check for diabetes or blood sugar control. Additionally, your urine will be tested for total glucose excreted over 24 hours, which helps assess how efficiently your kidneys filter glucose.
Why Is This Test Done?
Doctors may order this test if you have symptoms of diabetes (like frequent urination, extreme thirst), if your blood sugar levels are consistently high or low, or if you’re at risk due to family history or other health conditions.
What to Expect Before the Test
You’ll need to collect all your urine for 24 hours in a special container. Your blood will be drawn once (usually from a vein in your arm) to measure your current blood glucose level. Follow your doctor’s instructions carefully to ensure accurate results.
What Happens During the Test?
Blood is drawn to check your current blood glucose level. You’ll also collect all urine produced in a 24-hour period for glucose analysis. This helps track how much sugar your body removes through urine.

Frequently asked questions
This test helps diagnose diabetes by showing if your body can’t control blood sugar properly. High urine glucose may indicate poor kidney function or diabetes, while abnormal blood glucose levels can signal metabolic issues like hypoglycemia or insulin resistance.
Results typically take 1–3 business days, depending on lab processing. Your doctor will discuss them with you during your follow-up visit.
