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

Why HbA1c Matters in Diabetes Care

HbA1c reflects average blood sugar levels over the past 2–3 months by measuring the percentage of hemoglobin bound to glucose. It’s a key tool for diabetes management, helping doctors assess whether your treatment is effective and adjust it as needed.

Understanding Urinary Hemoglobin in Your 24-Hour Sample

The urine test checks for hemoglobin (the protein in red blood cells) that may have leaked into your urine, often due to kidney issues, bleeding disorders, or other conditions. This test helps identify hidden blood loss that isn’t visible in a routine urine dipstick.

How the Test Works: Combining Blood and Urine Data

Your blood sample is analyzed for HbA1c using standard methods (like high-performance liquid chromatography). Your 24-hour urine sample is tested for hemoglobin content, typically via immunoassay or nephelometry, to detect small amounts that might not be obvious otherwise.

Common Reasons for This Test

Doctors may order this test if you have diabetes and need to monitor both blood sugar control *and* check for conditions causing blood in urine, such as kidney disease, urinary tract infections, or bleeding disorders. It’s also used in research or specialized evaluations.
