The formula to calculate Urine Albumin to Creatinine Ratio (ACR) is:
\[ ACR = \frac{UA}{UC} \]
Where:
Albumin-to-creatinine ratio (ACR) is the first method of preference to detect elevated protein. The recommended method to evaluate albuminuria is to measure urinary ACR in a spot urine sample.
Urine Albumin (al-BYOO-min) is a protein found in the blood. A healthy kidney does not let albumin pass into the urine. A damaged kidney lets some albumin pass into the urine.
Urine Creatinine is a chemical waste product of creatine. Creatine is a chemical the body makes to supply energy, mainly to muscles.
Let's assume the following values:
Using the formula:
\[ ACR = \frac{UA}{UC} \]
Evaluating:
\[ ACR = \frac{0.2}{6} \]
The Urine Albumin to Creatinine Ratio is 0.0333333333333333.
