Why This Test Is Done

Your healthcare provider may order this test if you experience symptoms like fever, abdominal pain, or signs of infection (such as cloudy or foul-smelling fluid). It’s also used to assess how well your dialysis is working to remove waste and excess fluids from your body.

What to Expect Before the Test

No special preparation is needed. The fluid is collected through your peritoneal dialysis catheter during a routine dialysis session. You may feel mild discomfort, but it’s usually brief.

What the Test Measures

The test analyzes the fluid for signs of infection (e.g., white blood cells, bacteria), protein loss, glucose levels, and other markers that indicate how well your body is responding to dialysis or if complications are present.

Possible Results and Their Meaning

High white blood cells or bacteria may signal an infection, while abnormal protein or glucose levels could indicate poor dialysis function or fluid imbalance. Your provider will discuss results with you based on your symptoms and medical history.

Clinical interpretation

How abnormal results are interpreted and what conditions they suggest.
