* Early stage (60% function of normal) * Renal insufficiency (25% of normal) * End stage (less than 10% of normal) *Renal failure
41
What is chronic renal failure?
Damage to nephron impairs kidney's ability to perform normal functions.
42
What is the significance of Glomerular Filtration Rate (GFR) in chronic renal failure?
Classified by GFR, indicating the level of kidney function.
