Different tests can be used to provide valuable information about the function of the peritoneal membrane. The data obtained can be useful for tailoring dialysis adequacy, for the analysis of clinical problems such as ultrafiltration failure or to predict the development of more severe peritoneal membrane derangement. The most widely used peritoneal function test is the peritoneal equilibration test (PET), developed and described by Twardowski in 1987. PET is performed using a 2.27% glucose solution, and it lasts 4 hours. It measures peritoneal solute transport and ultrafiltration (UF), and it gives the possibility to categorize patients (high, high-average, low-average and low transporters). However, a PET with 3.86% glucose provides better information on UF, on th...
