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
