Description

The albumin:creatinine ratio (ACR) is a clinical test used to measure the amount of albumin in a patient's urine. Albumin is a protein that is normally found in the blood, but when it is found in the urine, it can be an indication of kidney disease. The ACR test is used to measure the amount of albumin in the urine relative to the amount of creatinine, which is a waste product that is normally found in the urine.

The ACR test is typically performed by collecting a urine sample from the patient. The sample is then sent to a laboratory for analysis. In the laboratory, the sample is tested for albumin and creatinine levels. The ratio of albumin to creatinine is then calculated and reported as the ACR. The ACR test is a simple and non-invasive way to measure the amount of albumin in the urine and can be used to help diagnose and monitor kidney disease.
