Patient's Query

I've heard I should regularly test urine albumin levels to catch diabetic kidney damage early. How frequently should I have this test done? Is the urine albumin-to-creatinine ratio test sufficient for accurate results?

Yes, regularly testing urine albumin levels is crucial for early detection of diabetic kidney disease (nephropathy).

Recommended screening frequency:

  • Type 2 diabetes: Start testing at diagnosis, then annually.

  • Type 1 diabetes: Begin annual screening five years after diagnosis.

A spot urine albumin-to-creatinine ratio (ACR) is the standard recommended test because it’s convenient and reliable. Normal ACR is typically below 30 mg/g; results between 30–300 mg/g indicate early kidney issues ("microalbuminuria"), prompting closer monitoring and possible treatment adjustments.

If elevated results:

  • Confirm with repeat tests within 3–6 months.

  • Intensify glucose and blood pressure control to protect kidney function.

  • Consult nephrologists if abnormalities persist.

Discuss personalized screening plans with your diabetes care team based on your results and health status.
