What is this test?

This test measures the amount of high-density lipoprotein (HDL) cholesterol in dialysis fluid. HDL is one of the cholesterol-containing particles carried in blood, but this test examines fluid used for dialysis rather than a blood sample.

Why might I need this test?

It may be ordered in selected situations to assess the lipid composition of dialysis fluid. The result is usually interpreted with other measurements of the fluid and is not commonly used by itself to diagnose a condition.

How is the test performed?

A laboratory analyzes a sample of dialysis fluid using a validated method that specifically measures HDL cholesterol. The result is reported as a substance concentration, meaning the amount of cholesterol in a given volume of fluid.

How do I prepare for the test?

This test generally does not require fasting because it is performed on dialysis fluid rather than blood. Follow your dialysis team's instructions about sample collection, handling, and timing.

Reference range

Adult males: >40 mg/dL; Females: >50 mg/dLN/A

Specimen: serum

Fasting for 12-14 hours preferred. Water is permitted. Avoid alcohol for 24 hours before the test.

Clinical interpretation

How abnormal results are interpreted and what conditions they suggest.

Frequently asked questions

Is this the same as a routine HDL blood test?
No. A routine HDL cholesterol test measures HDL in blood, while this test measures HDL cholesterol in dialysis fluid.
Do I need to fast before this test?
Fasting is generally not required because the specimen is dialysis fluid, not blood. Collection instructions from the dialysis team take priority.
What does an abnormal result mean?
It may indicate that the fluid's lipid composition differs from the expected level, but interpretation depends on the dialysis type, sample handling, and other available results. Your clinician or dialysis team can explain the result in your specific situation.
