Why This Test Is Done
Your healthcare provider may order this test if you’re undergoing peritoneal dialysis to monitor how well your body is clearing waste products and excess fluids from your blood through the peritoneal cavity. It can also help identify if certain substances are not being removed efficiently, which may affect your treatment plan.
What to Expect Before the Test
No special preparation is needed for this test. You’ll have a small catheter inserted into your peritoneal cavity during your usual dialysis session. The fluid collected (dialysate) will be sent to the lab for analysis.
What the Test Results Mean
Results show the concentration levels of specific substances in your peritoneal dialysate. These levels help determine if your dialysis is working as intended. Abnormal results may indicate issues like inadequate waste removal or fluid balance problems.
Common Conditions Monitored
This test is primarily used to monitor peritoneal dialysis effectiveness in patients with kidney disease. It may also help assess metabolic balance, electrolyte levels, or other dialysate-related parameters.
Clinical interpretation
How abnormal results are interpreted and what conditions they suggest.
