Hemoglobin A1c (HbA1c) with 24-hour urine collection for total urinary protein excretion

What This Test Measures

The **HbA1c** test reflects your average blood sugar levels over time by measuring the percentage of hemoglobin (the oxygen-carrying protein in red blood cells) that is coated with sugar. This provides a snapshot of how well your blood sugar has been controlled over months, rather than just recent days. Higher levels may indicate poor diabetes management or undiagnosed diabetes.

Why Urine Protein Is Included

The 24-hour urine protein test assesses how much protein your kidneys filter into your urine. Elevated protein levels can signal kidney damage or disease, especially in people with diabetes. Together, these tests help doctors monitor both blood sugar control and kidney function in people at risk for complications.

When This Test Is Ordered

Your doctor may order this test if you have diabetes, prediabetes, or symptoms like frequent urination, swelling, or fatigue. It’s also used to check kidney health in people with diabetes or those with high blood pressure or family history of kidney disease.

What to Expect Before the Test

For the urine protein part, you’ll collect all urine for 24 hours in a special container. For the HbA1c, no special prep is needed, but you may be asked to fast or avoid certain medications. Follow your doctor’s instructions carefully to ensure accurate results.
