Overview
The purpose of this test is to formally evaluate the peritoneal membrane transport characteristics, measure the transfer rates of creatinine and glucose, and assess dialysis adequacy through solute clearance tracking. It helps nephrologists classify patients as low, low-average, high-average or high transporters, tailor CAPD or CCPD prescriptions, and ensure efficient dialysis dosing.

Sample Collection
No special preparation required. Continue dialysis as prescribed. Inform your doctor about any active infections or recent changes in medication.
Method: Timed collection of peritoneal dialysate at 0, 2, 4 hours, overnight and 24 hours; 24-hour urine; paired blood samples
Laboratory Analysis
Timed peritoneal dialysate collections are done at 0, 2, 4 hours, overnight, and 24 hours. A 24-hour urine collection is required. Blood samples (serum and plasma) are collected at the appropriate time during dialysis.
Report Delivery
All samples should be shipped refrigerated. Do not freeze. The laboratory will process samples for spectrophotometric analysis.
Timeline: Reports are typically available within 24 hours after the laboratory receives the samples.
Patient Instructions
About This Test
Who Should Get This Test
The purpose of this test is to formally evaluate the peritoneal membrane transport characteristics, measure the transfer rates of creatinine and glucose, and assess dialysis adequacy through solute clearance tracking. It helps nephrologists classify patients as low, low-average, high-average or high transporters, tailor CAPD or CCPD prescriptions, and ensure efficient dialysis dosing.
How to Prepare
- Collect peritoneal dialysate in sterile screw-capped containers at the specified time points: 0 hour, 2 hours, 4 hours, overnight, and 24 hours.
- Collect 24-hour urine in a clean sterile container; measure and record the total volume.
- Collect 2 mL serum in an SST and 2 mL plasma in a Grey Top (sodium fluoride) tube.
- Label all containers clearly with patient name, time point, and collection date.
- Ship samples refrigerated immediately. Do not freeze.
Doctor's Notes
Reviewed by Dr Ramarao Paidisetty — MBBS, MD (Biochemistry) · Reg. No. 21504
"The PET test is essential for personalizing dialysis prescriptions and monitoring peritoneal membrane function over time. It helps us tailor therapy to each patient's unique transport characteristics."

Test Parameters & Specifications
Sample Stability
- Frozen samples
- Hemolyzed blood samples
- Improperly labeled containers
- Incorrect or unspecified collection time points
- Samples received in wrong container type
Understanding Your Results
Slow solute transfer; longer dwell times may be beneficial; risk of inadequate clearances with short cycles.
Generally suitable for standard CAPD or CCPD; monitor adequacy.
Typical transporter status; standard dialysis regimens are often effective.
Rapid solute transfer but rapid glucose absorption leading to loss of ultrafiltration; short dwell cycles or alternative modalities may be needed.
If you experience fatigue, swelling, nausea, reduced urine output, or other signs of inadequate dialysis, or if your PET results indicate high or low transporter status and your dialysis prescription needs adjustment, consult your nephrologist as soon as possible.
Risks & Considerations
- ●Minimal discomfort from blood draw
- ●Risk of bruising or infection at venipuncture site
- ●No major risks associated with dialysate collection as it is through the existing dialysis catheter
Interfering Factors
- ●Active peritonitis or recent peritoneal infection
- ●Incomplete collection of dialysate or urine
- ●Incorrect timing of dwell periods or sampling
- ●Recent administration of substances affecting glucose or creatinine measurement
- ●Improper sample storage, especially freezing or delayed transport
