We thank you for your question. There really is no formal research that we are aware of on this topic of how missing a PD treatment would affect the Kt/V (peritoneal dialysis adequacy) results. Likely, missing one treatment would increase the patient’s urea to higher than would be normal for that patient, and thus would affect the lab results on the 24-hour collection, especially if the missed treatment was just before the scheduled PD adequacy testing.

From an informal poll of members of the ISPD Nursing Liaison Committee, responses varied. A local practice was that the test would be rescheduled if a treatment was missed in the week prior to the test. Others felt it was possibly okay to go ahead with the test. However, there was overall concern that if the patient had missed one treatment, then perhaps the patient had also missed other treatments and this possibility should be discussed with the patient and the patient’s concerns/issues addressed.
