Stage1 (Corrected Ccr > 25 cc/min, albumin normal) - Should try to prevent renal disease progression

Stage 2a (Corrected Ccr =20 to 25 cc/min, albumin normal, Hct <37 Male, Hct <33 Female) - Consider early placement of AV fistula

Stage 2b (GFR=17 to 20 cc/min, albumin = or <4.0 but not decreasing) - Access should be in place

Stage 3 (Corrected Ccr 14 to 20 cc/min Krt/V= < 2.0 AND albumin = or < 4.0 and decreasing and/or nPNA<.8 g/d/kg) - Start PD to bring Krt/V to 2.0

Stage 4 (ESRD- Corrected Ccr 7 - 14 and Krt/V<2.0 AND albumin <4.0 and decreasing at 0.1 gm/mo and/or nPNA <.8) - Renal replacement therapy
