Hemoglobin A1c (HbA1c) measured in urine

Why Might This Test Be Ordered?

Your healthcare provider may order this test if you have diabetes, are at risk for diabetes, or if they suspect conditions like hemolytic anemia (where red blood cells break down faster than usual). It can also help assess how well your blood sugar is being controlled over time.

How Is the Test Performed?

A urine sample is collected, typically through standard urine collection methods (e.g., midstream clean-catch or timed 24-hour collection, depending on clinical context). The sample is then analyzed in the lab using an immunoassay method to detect hemoglobin A1c.

What Does the Result Mean?

Hemoglobin A1c in urine is not a standalone diagnostic test for diabetes but may be part of a broader evaluation. Elevated levels could suggest conditions affecting red blood cell turnover or prolonged high blood sugar, but results should be interpreted alongside clinical findings and other tests.

Common Causes of Abnormal Results

Results may vary due to factors like red blood cell destruction (e.g., hemolytic anemia), certain medications, or conditions that alter urine composition. False positives or negatives can occur, so results should be reviewed by a healthcare provider.
