Reference Range
The American Diabetes Association defines increased urine albumin excretion as follows:
Because of variability in urinary albumin excretion, ADA recommendations specify that 2-3 specimens, collected within a 3-6 month period, should exhibit abnormality prior to diagnostic consideration.
| Category | Spot Collection (mg/g creatinine) |
| Normal | <30 |
| Moderately Increased | 30-299 |
| Clinical Albuminuria | >=300 |
Because of variability in urinary albumin excretion, ADA recommendations specify that 2-3 specimens, collected within a 3-6 month period, should exhibit abnormality prior to diagnostic consideration.
Clinical Significance
The Microalbumin:Creatinine Ratio test is used to help screen for conditions such as high blood pressure or diabetes which can cause kidney damage. Because creatinine usually is filtered out of the body in the urine at a constant rate, the Microalbumin:Creatinine Ratio can provide more accurate results than a measure of Microalbumin by itself.
