Urine Microalbumin-to-Creatinine Ratio (Microalbumin-to-Creatinine Ratio)

Why This Test Matters for Kidney Health

Albumin is normally filtered by the kidneys and excreted in urine. Small amounts of albumin in urine can signal early kidney damage, even before other signs appear. This test is particularly useful for monitoring kidney function in people with diabetes or high blood pressure, as these conditions can damage kidneys over time. Early detection allows for timely management to slow progression.

What to Expect During the Test

You’ll provide a urine sample (typically a midstream clean-catch or catheterized sample) in a sterile container. The lab will analyze the urine for albumin and creatinine levels. No special preparation is needed, but drinking extra water before the test may help dilute urine for more accurate results.

How the Results Are Used

Your results are compared to a reference range (not provided here) to determine if albumin levels are elevated. An elevated ratio may indicate early kidney problems, prompting further testing or lifestyle changes (like blood pressure control or diabetes management). Doctors may also recommend follow-up tests if needed.

Common Causes of Abnormal Results

Elevated microalbumin-to-creatinine ratios can occur due to diabetes, high blood pressure, kidney disease, or other conditions that damage kidney function. Low results are less common but may occur in healthy individuals or those with certain kidney conditions.
