ACR Calculator



The Albumin to Creatinine Ratio (ACR) is a crucial indicator used in medical assessments to evaluate kidney function and detect potential kidney problems. It measures the ratio of albumin (in milligrams) to creatinine (in grams) in a urine sample. Monitoring ACR can help identify kidney disease, diabetes-related kidney damage, and other health conditions.

How to Use the ACR Calculator

Using our ACR Calculator is simple. Just follow these steps:

  1. Input the albumin value in milligrams (mg).
  2. Input the creatinine value in grams (g).
  3. Click the “Calculate” button to obtain the ACR result in mg/g.


The formula to calculate the Albumin to Creatinine Ratio (ACR) is:

ACR = Albumin (mg) / Creatinine (g)


Let’s say you have the following values:

  • Albumin: 30 mg
  • Creatinine: 0.8 g

Using the ACR formula:

ACR = 30 mg / 0.8 g ACR ≈ 37.5 mg/g

So, the ACR for this sample is approximately 37.5 mg/g.

Frequently Asked Questions

1. What does a high ACR value indicate?

  • A high ACR value may suggest kidney damage or dysfunction. It could be indicative of conditions like diabetes, hypertension, or kidney disease.

2. Is it necessary to have ACR tested regularly?

  • Regular ACR testing is advisable for individuals at risk of kidney-related issues, such as those with diabetes or hypertension. Consult your healthcare provider for personalized guidance.

3. How can I lower my ACR if it’s too high?

  • Lifestyle changes like managing blood sugar levels, maintaining a healthy diet, and controlling blood pressure can help lower ACR. Consult a healthcare professional for specific recommendations.

4. Are there any limitations to the ACR calculation?

  • ACR results can be affected by factors like diet and hydration. It’s essential to follow your healthcare provider’s instructions for accurate testing.


The ACR Calculator simplifies the process of determining the Albumin to Creatinine Ratio, a vital metric in assessing kidney function and related health conditions. By understanding how to use the calculator, the underlying formula, and interpreting results, you can effectively monitor your health or assist others in doing so. Regular ACR assessments are essential for early detection and management of kidney-related issues.
