ACR Calculator

Calculate the urine albumin-to-creatinine ratio (ACR / UACR) in mg/g from urine albumin and urine creatinine. Choose mg/dL, mg/L, or g/L units and see published interpretation bands with a medical disclaimer.

Match the unit selector to your lab report.

Must be greater than 0, since it is the denominator of the ratio.

Common use limits

This calculator converts urine albumin and urine creatinine to mg/dL before dividing, then reports the ratio in mg/g using common published interpretation bands.

The output is a screening estimate. It does not diagnose kidney disease and does not replace a repeat test or an eGFR-based kidney health assessment.

This ACR calculator provides educational arithmetic and is not medical advice, a diagnosis, or a substitute for laboratory reporting. Do not use it to diagnose or rule out kidney disease, change medication, or delay follow-up. Review an abnormal, unexpected, or changing result with a qualified healthcare professional, who may consider repeat testing, eGFR, blood pressure, diabetes, symptoms, and other findings. Seek prompt medical care for severe illness, markedly reduced urine, swelling with breathing trouble, confusion, or other urgent symptoms.
