Patients to be tested :
- those with eGFR < 60 ml/min
- patients with diabetes with any level of eGFR
For the initial detection of proteinuria, if the ACR is between 3 mg/mmol and 70 mg/mmol, this should be confirmed by a subsequent early morning sample.
If the initial ACR is 70 mg/mmol or more, a repeat sample need not be tested.
A confirmed ACR of 3 mg/mmol or more is clinically important proteinuria
