About This Test
Who Should Get This Test
PET measures the equilibration of solutes across the peritoneal membrane and is used to categorize patients based on peritoneal transport characteristics. It aids in tailoring peritoneal dialysis prescriptions and monitoring membrane health over time.
How to Prepare
- Dialysate samples should be collected in sterile screw-capped containers at timed intervals (0, 2, 4 hours, overnight).
- Blood samples (2 mL serum and 2 mL plasma) should be collected at the 2-hour time point.
- Ship all samples refrigerated; do not freeze.
- Samples must be labeled with the exact collection time.
Doctor's Notes
Reviewed by Dr SHAILAJA RAGHUNATH MURDESHWAR — MBBS, MD (General Medicine) · Reg. No. 8052
"The Peritoneal Equilibrium Test is a cornerstone for individualizing peritoneal dialysis. It helps identify the patient's peritoneal transport type, allowing us to choose the most appropriate dialysis regimen for better adequacy and outcomes."

Understanding Your Results
If you are undergoing peritoneal dialysis and experience symptoms such as persistent abdominal pain, fever, nausea, vomiting, unexplained weight gain or loss, or cloudy dialysate fluid, consult your nephrologist immediately. PET should be performed annually or as directed by your doctor.
Limitations
- ⚠PET is an assessment tool and not a confirmatory diagnostic test
- ⚠Results may vary with patient's hydration status
- ⚠Requires meticulous sample timing and labeling
- ⚠Cannot be used in patients with recent abdominal surgery or active peritonitis
Risks & Considerations
- ●Bleeding or bruising at the venipuncture site
- ●Infection from puncture site (rare)
- ●Minimal discomfort during blood draw
Interfering Factors
- ●Presence of peritonitis
- ●Recent abdominal surgery
- ●Dehydration or volume overload
- ●Inaccurate timing of sample collection
- ●Use of certain antibiotics like aminoglycosides
