Hemoglobin A1c (HbA1c) with 24-hour urine collection for measurement of microalbumin excretion
This test measures your blood sugar control over time and checks for small protein losses in urine, which can signal kidney issues. It’s often used in people with diabetes or high risk for kidney problems.

Why This Test Matters for Diabetes Management
HbA1c reflects your average blood sugar levels over the past 2–3 months, giving doctors a clearer picture than daily glucose checks alone. It’s a key tool for adjusting diabetes treatments and preventing complications like nerve damage or kidney disease.
How Microalbumin in Urine Works
Microalbumin is a small protein that normally stays in your bloodstream. When kidneys are damaged (even before symptoms appear), they may leak it into urine. Detecting microalbumin helps identify early kidney problems in people with diabetes or other risk factors.
What to Expect Before Your Test
For this test, you’ll provide a blood sample (for HbA1c) and a 24-hour urine collection (for microalbumin). Follow your doctor’s instructions carefully—this may include timing your urine collection or fasting for the blood draw. Avoid certain medications or foods that could affect results.
What the Results Mean
Results are interpreted together: HbA1c shows long-term blood sugar control, while microalbumin levels indicate kidney function. High microalbumin may signal kidney strain, while elevated HbA1c suggests poor diabetes management. Your doctor will discuss these findings with you.
Clinical interpretation
How abnormal results are interpreted and what conditions they suggest.
Clinical significance: Elevated HbA1c (>7%) indicates poor glycemic control and increases diabetes-related risks (e.g., neuropathy, cardiovascular disease). Persistently high microalbumin (>30 mg/24h) suggests early kidney damage, often reversible with diabetes management or kidney-protective therapies.
