Despite being common, CKD often remains undiagnosed partly because of lack of symptoms until late in the disease process. Late detection of CKD, and hence lack of effective management, increases the risk of progression to end-stage renal disease which often requires renal replacement therapy such as dialysis or transplantation. Derangement in serum creatinine and eGFR will alert a clinician to a patient with potential CKD. Timely referral for specialist nephrology input when required is key.
