Hemoglobin A1c (HbA1c) with 24-hour urine collection for quantitative measurement of glycated hemoglobin and urinary albumin
This test measures your average blood sugar levels over the past 2–3 months and checks for kidney function by testing for small amounts of protein in your urine.

Why This Test Matters for Diabetes Control
HbA1c reflects your blood sugar levels over time, giving doctors a clearer picture of how well your diabetes is managed. It’s a key tool for adjusting treatment plans, such as medication or diet.
How Urinary Albumin Detects Kidney Stress
Small amounts of albumin (a protein) in urine can indicate early kidney damage, which is common in people with diabetes. This test helps identify if your kidneys are at risk before symptoms appear.
What to Expect Before the Test
You’ll collect a 24-hour urine sample (starting and ending at the same time) to measure albumin. Blood is drawn to measure HbA1c. Follow your doctor’s instructions for timing and sample collection.
What the Results Mean
HbA1c results (typically reported as a percentage) show average blood sugar levels. Urine albumin results indicate protein loss, which may signal kidney strain. Both results together help assess diabetes and kidney health.
Reference range
Adult males: 13.5-17.5 g/dL; Females: 12.0-16.0 g/dLN/A
No special preparation usually required. Stay well hydrated. Inform your healthcare provider of all medications and supplements you are taking.
Clinical interpretation
How abnormal results are interpreted and what conditions they suggest.
This test is critical for diabetes care because it provides long-term blood sugar trends and early kidney risk detection. High HbA1c or albumin levels may prompt lifestyle changes, medication adjustments, or further testing.
Short name
HbA1c + Urinary Albumin (24h)
