Enter the albumin and the creatinine into the Calculator. The calculator will evaluate the Albumin to Creatinine Ratio. 

Albumin to Creatinine Ratio Formula

ACR = ALB / CR

Variables:

  • ACR is the Albumin to Creatinine Ratio (mg/g)
  • ALB (mg) is the albumin
  • CC (g) is the creatinine

To calculate Albumin to Creatinine Ratio, divide the total albumin by the total creatinine.

How to Calculate Albumin to Creatinine Ratio?

The following steps outline how to calculate the Albumin to Creatinine Ratio.

  1. First, determine the albumin. 
  2. Next, determine the creatinine. 
  3. Next, gather the formula from above = ACR = ALB / CR.
  4. Finally, calculate the Albumin to Creatinine Ratio.
  5. After inserting the variables and calculating the result, check your answer with the calculator above.

Example Problem : 

Use the following variables as an example problem to test your knowledge.

albumin = 50

creatinine = 24

FAQs about Albumin to Creatinine Ratio

What is the significance of the Albumin to Creatinine Ratio in medical diagnostics?

The Albumin to Creatinine Ratio (ACR) is an important marker used in the diagnosis and monitoring of kidney diseases. A higher ACR indicates abnormal kidney function, as it shows that the kidneys are allowing the leakage of albumin into the urine, which is not typical.

How often should the Albumin to Creatinine Ratio be tested in patients with kidney disease?

For patients with existing kidney disease or those at high risk, healthcare providers might recommend ACR testing at least once a year. However, the frequency can vary based on the patient’s condition, risk factors, and the doctor’s assessment.

Can lifestyle changes impact the Albumin to Creatinine Ratio?

Yes, lifestyle changes such as maintaining a healthy diet, regular exercise, controlling blood sugar and blood pressure, and avoiding substances harmful to the kidneys (like NSAIDs and certain antibiotics) can improve kidney function and potentially lower the ACR.

Is the Albumin to Creatinine Ratio test different for children compared to adults?

While the ACR test procedure is the same for both children and adults, the interpretation of results may differ. Children’s normal ACR values can be lower than adults’, and the ranges can vary with age. It’s important for healthcare providers to consider age-specific reference ranges when interpreting ACR results for children.
