The peritoneal equilibrium test is an indicator to assess the adequacy of peritoneal dialysis, and the regimen of peritoneal fluid is adjusted according to the results of the peritoneal equilibrium test to achieve optimal peritoneal dialysis results. The peritoneal equilibrium test has four results: the first is a high mean transit. The second is a low mean transit. The third is high transit. The fourth is low transit. For patients with high mean transit and low mean transit, the results are still better, so if it is high mean and low mean transit, there is no need to adjust the peritoneal dialysis protocol. For patients with low transit, i.e., poorer clearance of toxins and better clearance of water, i.e., better ultrafiltration, the dose of peritoneal dialysis fluid can be increased or the duration of peritoneal fluid storage can be extended for detoxification.
