Microalbumin Creatinine Ratio (ACR) Urine is a test that measures the amount of albumin relative to creatinine in a urine sample. It helps detect small amounts of albumin leakage that may indicate early kidney damage. The test is particularly useful for screening and monitoring kidney health in people with diabetes, hypertension, or other conditions that increase the risk of chronic kidney disease, often before symptoms develop.
It is commonly used to screen for and monitor kidney damage, particularly in people with diabetes, hypertension, or other conditions that increase the risk of kidney disease.
Albumin is a protein produced mainly by the liver. Healthy kidneys normally prevent most albumin from passing into the urine.
Creatinine is a waste product produced by normal muscle metabolism and eliminated through the kidneys. Measuring urine creatinine helps account for urine concentration when assessing albumin levels.
A higher-than-normal ACR may indicate increased leakage of albumin through the kidney's filtering system and can be an early sign of kidney damage.
Yes. Long-standing or poorly controlled hypertension can damage the kidneys and may result in increased urinary albumin.
