Albumin, Urine and Albumin to Creatinine Ratio (ACR)
Microalbumin, micral; ACR
To assist in the identification and management of early diabetes in order to avoid or delay onset of diabetic associated kidney disease.
There are no food, fluid, activity, or medication restrictions unless by medical direction. Either a random or a 24-hr urine collection may be ordered. As appropriate, provide the required urine collection container and specimen collection instructions.
Method: Immunoturbidometry for albumin, spectrophotometry for Cr.
|Albumin Creatinine Ratio (ACR)|
|Conventional Units||SI Units (Conventional Units x 0.113)|
|Normal||Less than 30 mg/g creatinine||Less than 3.4 mg/mmol creatinine|
|Clinically significant albuminuria||30–299 mg/g creatinine||3.4–33.8 mg/mmol creatinine|
|Overt albuminuria||Greater than 300 mg/g creatinine||Greater than or equal to 33.9 mg/mmol creatinine|
|Laboratory reports include the measured levels of random urine albumin and creatinine, and reporting units may vary between laboratories; reference ranges are often listed as "not established."|
