Peritoneal equilibration test in rapid versus slow transporters

Differences between rapid and slow transporters during PD. Rapid transporters reach creatinine equilibration more quickly (dialysate-to-plasma creatinine equals one, top panel); have a gradual reduction in dialysate volume after two hours due to glucose absorption (middle panel); and have a reduction in CCr after four hours due to absorption of creatinine with the glucose and fluid (lower panel). Thus, short dwell times are most efficient in these patients.
