What GFR threshold is commonly used to consider renal replacement therapy?

Renal replacement therapy is typically considered when kidney function has declined to a level where waste products, fluids, and electrolytes can no longer be managed with conservative care. That usually happens when the GFR falls to about 15 mL/min/1.73 m² or lower, marking the transition to end-stage kidney disease and prompting evaluation for dialysis or transplantation. At this point, uremic symptoms (like fatigue, nausea, and pruritus) and metabolic disturbances (such as hyperkalemia or metabolic acidosis) become more likely, and initiating RRT helps remove toxins and restore balance. Of course, the exact decision is individualized: some patients may start earlier if symptoms or complications arise, while others with slower progression may continue conservative management. The other options reflect earlier CKD stages or normal function, where dialysis is not indicated.
