The peritoneal equilibration test (PET) measures how effectively peritoneal dialysis is working. During peritoneal dialysis, a cleansing solution is infused into the abdomen of a person whose kidneys don't work, where it pulls wastes and extra fluids from the blood.

The solution contains dextrose or another sugar, salt and minerals dissolved in water. A catheter (soft tube) fills the abdomen with the solution. The solution mixes with wastes, salt and liquid, and all are removed when the solution drains out. This filling and removal process is called an exchange.

PET measures how much dextrose has been absorbed into the body from a bag of solution, and how much of the waste products urea and creatinine have flowed into the solution in a four-hour period. The rate at which dextrose is absorbed by the body and waste products move into the dialysis solution varies in different people. Those with higher rates may need to leave the dialysis solution in their abdomen for a shorter period so that they don't absorb too much dextrose and dialysis solution.
