PERITONEAL EQUILIBRIUM TEST (PET)*

People with kidney failure who are on peritoneal dialysis (PD), a type of dialysis involving cleansing of the blood without removing it from the body, will undergo a peritoneal equilibration test (PET) within a month or two after starting PD. The goal of the PET is to determine how well the peritoneal membrane, which lines the abdomen and helps filter waste and excess fluids from the body, is working.
