Albumin/Creatinine ratio (ACR)
The albumin/creatinine ratio (ACR) is a test that assesses the ratio of albumin to creatinine in urine, allowing for the evaluation of kidney function and the identification of early signs of kidney damage. It is primarily performed to monitor kidney diseases such as diabetes or hypertension, which can lead to increased excretion of albumin in the urine.

- Test description
The albumin/creatinine ratio (ACR) is a test that assesses the ratio of albumin to creatinine in urine, allowing for the evaluation of kidney function and early detection of kidney damage. The albumin/creatinine ratio (ACR) measures the amount of albumin excreted in the urine. Microalbuminuria, characterized by an ACR range of 30–300 mg/g, indicates endothelial dysfunction.
When should the test be performed?
This test is primarily performed to monitor kidney diseases such as diabetes or hypertension, which may lead to increased albumin excretion in urine. It is useful for detecting early diabetic nephropathy and as a marker of endothelial dysfunction and subclinical cardiovascular conditions.
Indications
The albumin/creatinine ratio (ACR) is measured for the diagnosis of conditions such as diabetes, diabetic nephropathy, hypertension, kidney diseases, urinary tract infections, multiple organ failure, and respiratory failure.
