Staging of CKD

The estimated GFR, which helps clinicians determine how well the kidneys are filtering waste, is used in the staging of CKD. The National Kidney Foundation defines CKD as either kidney damage, identified by markers in the urine or blood or by imaging, with or without changes in the GFR, or a GFR <60 mL/min/1.73 m2 for a minimum of 3 months.[9] Table 1 depicts the staging criteria as determined by the Kidney Disease Outcomes Quality Initiative (K/DOQI) guidelines.[9]
