What effect does glucose have on measured creatinine in the peritoneal equilibration test?
Very high glucose concentrations falsely elevate measured creatinine. An appropriate correction factor may be applied to obtain an accurate creatinine value; however, the glucose interference is of a low magnitude in most dialysate samples at a 4-hour dwell time. Clinical interpretation of the peritoneal equilibration test using uncorrected creatinine values to determine the dialysate-to-plasma ratio at 4 hours is associated with minimal error.
