REFERENCE RANGES:​

​

Males & Females >= 1 year of age:

​​

Microalbumin (MALB): Not Established (mg/L)

​

Reference intervals are not established for isolated urine microalbumin results. Interpret in conjunction with albumin-to-creatinine ratio (ACR) and clinical context.

​

Creatinine, Urine (uCREA): Not Established (mg/dL)

​

Reference intervals are not established for isolated urine creatinine results. Interpret in conjunction with MALB / Creatinine or uPRO / Creatinine ratios and clinical context.

​

MALB / Creatinine Ratio (MCR): < 30 (mg/g)

​​

​Calculated using the following formula: (MALB / CREAU) * 100
