Clinical Significance of the Urine Microalbumin-to-Creatinine Ratio
Disease description:
I went to the hospital for a physical examination two days ago and collected my test report today. On the report, I noticed a value labeled “urinary microalbumin-to-creatinine ratio.” What is the clinical significance of this ratio?

The urine microalbumin-to-creatinine ratio (UACR) reflects an individual’s kidney function. Abnormally high or low values suggest renal impairment. In healthy individuals, the UACR is typically less than 30 mg/g. A value exceeding 30 mg/g indicates significant albuminuria and may be associated with conditions such as nephropathy or diabetic kidney disease. Patients with elevated UACR should maintain a light, low-salt diet and ensure adequate hydration.
