GFR CKD: Staging Flashcards
GFR Range: G1
≥ 90 mL/min
Normal
GFR Range: G2
60-89 mL/min
Mildly decreased
GFR Range: G3a
45-59 mL/min
Mild –> moderately decreased
GFR Range: G3b
30-44 mL/min
Moderate-severely decreased
GFR Range: G4
15-29 mL/min
Severely decreased
GFR Range: G5
Albuminuria Categories: A1
ACR ≤ 30mg/g (≤ 3mg/mmol)
Normal
Albuminuria Categories: A3
ACR ≥300mg/g (>30mg/mmol)
Albuminuria
MDRD Limitations (6)
- ) Amputees

Wt for C-G if BMI > 40?
Lean BW (kg)
= (9270)(Total BW) / [6680 + (216 * BMI)] FOR MEN
= (9270)(Total BW) / [8780 + (244 * BMI)] FOR WOMEN
Wt for C-G if BMI 30-40?
Adjusted BW (kg)
= Ideal BW + [0.4 * (Actual BW - Ideal BW)]
Ideal BW
Men = 50kg + (Ht > 60in * 2.303) Women = 45kg + (Ht > 60in * 2.303)
Nephritic Kidney Disease: Diagnosis
Hematuria
Proteinuria (~1-3g/day)
