Answer

In an update of its CKD classification system, the NKF advised that GFR and albuminuria levels be used together, rather than separately, to improve prognostic accuracy in the assessment of CKD. [3] More specifically, the guidelines recommended the inclusion of estimated GFR and albuminuria levels when evaluating risks for overall mortality, cardiovascular disease, end-stage kidney failure, acute kidney injury, and the progression of CKD. Referral to a kidney specialist was recommended for patients with a very low GFR (< 15 mL/min/1.73 m²) or very high albuminuria (> 300 mg/24 h). [3]
