The GFR Clock for Staging CKD Staging CKD is most frequently done by calculating the estimated glomerular function rate (eGFR) as a proxy for kidney function. These calculations are often based on a patient’s serum creatinine (a muscle metabolite that is filtered in the kidney). After calculating the eGFR, CKD can be staged into 1 of 5 stages. Using the GFR clock is one way to remember the eGFR cut-offs for each CKD stage. Credit- @JustinBerk #Diagnosis #Nephro #CKD #EGFR #Staging #Stages #Clock #Mnemonic
