Microalbumin / Creatinine Ratio
What It Is
The ACR measures small amounts of albumin in the urine relative to creatinine, detecting early kidney damage.
Why It Matters
Microalbuminuria is one of the earliest signs of diabetic kidney disease and can prompt early intervention.
If Levels Are High
Elevated ACR indicates increased albumin leakage from the kidneys, suggesting early nephropathy.
If Levels Are Low
A normal ACR indicates healthy kidney filtration with no abnormal protein loss.
Preparation
First morning urine sample is preferred.
How Often to Test
Annually for those with diabetes or hypertension.
