Online calculator to calculate Urine albumin to creatinine ratio (ACR), helps to identify kidney disease that can occur as a complication of diabetes by using ACR ratio formula.
Albumin : creatinine ratio: It is ratio of urinary albumin to urinary creatinine; usually it is expressed as milligram of albumin excreted per gram of urinary creatinine.
| Stage of nephropathy | Urine dipstick for protein | Urine ACR(mg/mmol) | 24-urine collection for albumin*(mg/day) |
|---|---|---|---|
| Normal | Negative | < 2.0 (men) < 2.8 (women) | <30 |
| Microalbuminuria | Negative | 2. 0 - 20.0 (men) 2.8 - 28.0 (women) | 30-300 |
| Overt nephropathy (Macroalbuminuria) | Positive | > 20.0 (men) > 28.0 (women) | >300 |
Note : (*) Values are for urinary albumin, not total urinary protein, which will be higher than urinary albumin levels.
Formula:
ACR (Albumin : Creatinine Ratio) = Albumin / Creatinine
