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]
