- <15 mg/mmol Creatinine = Normal
- 15 – 49 mg/mmol Creatinine = Trace Proteinuria. Consider ACEI or ARB in diabetes.
- 50 – 99 mg/mmol Creatinine = Significant proteinuria. Repeat using early am sample. Consider ACEI or ARB in hypertension.
- 100 – 300 mg/mmol Creatinine = High proteinuria. If new finding, seek nephrology advice regardless of eGFR.
- >300 mg/mmol Creatinine = “Nephrotic range” proteinuria. If new finding, seek nephrology advice regardless of eGFR.
Proteinuria is a risk factor for cardiovascular disease and for decline in GFR in CKD
UK CKD Guidelines suggest if PCR is >100 mg/mmol patient should be referred to Nephrologists irrespective of GFR.
