Send dialysate fluid for cell count, Gram stain, culture (if available)
Cell count >100/mm3 with >50% neutrophils most consistent with infection

There must be dialysis fluid "dwelling" within the patient for adequate fluid collection.  If the patient is not "dwelling" then coordination with nephrology is required to infuse fluid to be used to sample the peritoneum. Fluid may be required to "dwell" for a few hours prior to collection.
Perform only if necessary as part of the abdominal pain workup, to rule-out other (secondary) causes of<unk> 
CT WITHOUT IV contrast
Patients are dependent on small amounts of residual renal function and thus risk of contrast outweighs benefits

Peritoneal dialysis-associated peritonitis
Abdominal pain standard differential also applies to patients with peritoneal dialysis, in addition to concern for peritonitis
Spontaneous bacterial peritonitis
Dialysis-associated hypotension
Abdominal compartment syndrome
Dialysis disequilibrium syndrome
Ureteral stent complications
Air embolism
