What is this test?

This test measures the concentration of cholesterol in dialysate fluid, which is the solution used for peritoneal dialysis. It is different from a routine cholesterol blood test.

Why might I need this test?

A clinician may order this test to evaluate the composition of a dialysis fluid sample. The result may be relevant when monitoring peritoneal dialysis or investigating an unexpected fluid finding.

How is the test performed?

A sample of the specified dialysis fluid is collected according to the dialysis team's instructions and analyzed by a laboratory. The laboratory method is not identified by the test abbreviation, so the report should be reviewed for the method and units used.

How do I prepare for the test?

Collect or provide the fluid exactly as directed by your dialysis team, including the specified timing and container. Do not substitute a blood sample, and ask whether fasting or any other preparation is required.

Clinical interpretation

How abnormal results are interpreted and what conditions they suggest.

Frequently asked questions

Is this the same as a routine blood cholesterol test?
No. This test measures cholesterol in dialysate fluid, whereas a routine lipid panel measures cholesterol in blood.
Do I need to fast before this test?
Fasting is generally not relevant to a dialysate fluid test, but follow the instructions provided by your dialysis team. Preparation requirements depend on how and when the fluid is collected.
Why was my dialysate fluid tested for cholesterol?
Reasons can vary, including monitoring the dialysis fluid or investigating an unexpected finding. Ask your clinician to explain the purpose of the test in your specific situation.
