  • CKD stages 1 and 2 are defined by evidence of kidney damage (+), while CKD stages 3–5 are defined by reduced eGFR with or without evidence of kidney damage (+/–).

  • * Kidney damage is most often manifest as albuminuria (UACR30 mg/g Cr) but can also include glomerular hematuria, other abnormalities of the urinary sediment, radiographic abnormalities, and other presentations.

  • ** Risk factors for CKD progression include elevated blood pressure, glycemia, and albuminuria.
