- To subject to or undergo dialysis or hemodialysis.
- The separation of the smaller molecules in a solution from the larger molecules by passing the solution through a membrane that does not allow the large molecules to pass through.
- A medical procedure in which this technique of molecular separation is used to remove metabolic waste products or toxic substances from the blood. Dialysis is required for individuals with severe kidney failure.
