What is the GFR threshold for stage 5 kidney disease?

Explanation:
GFR stage 5 means kidney failure, defined by a GFR below 15 mL/min/1.73 m². At this level, kidneys can no longer maintain homeostasis, so renal replacement therapy (dialysis or transplant) is typically needed. Normal GFR is about 90–120; the stages progress as follows: stage 2 is 60–89, stage 3 is 30–59, and stage 4 is 15–29. Values above 15 indicate less severe disease, while below 15 marks the threshold for stage 5.
