Peritoneal equilibration test

Time-dependent changes during peritoneal dialysis in dialysate concentration (D) of glucose (left panel) or creatinine (right panel) as a proportion of original dialysate glucose concentration (DO) or plasma creatinine concentration (P), respectively. The absorption of glucose from the dialysate gradually lowers the D/DO ratio, while the diffusion of creatinine into the dialysate raises the D/P ratio. Slow transporters may be inadequately dialyzed due to diminished solute removal. Rapid transporters can achieve a D/P creatinine ratio above 0.8 and a D/DO glucose below 0.3 at 4 hours; they may be predisposed to malnutrition from increased protein losses in the dialysate and to decreased fluid removal due to absorption of glucose.
