What is this test?

Cholestanol, also called cholestan-3-ol, is a compound related to cholesterol. This test measures its mass concentration in the specimen identified on your laboratory order.

Why might I need this test?

The test may be ordered to evaluate cholesterol or bile-acid metabolism, particularly when symptoms or other findings suggest a liver, metabolic, or inherited condition.

How is the test performed?

A laboratory sample is collected and analyzed using a validated quantitative method. The laboratory report provides the measured amount of cholestanol together with any reference information appropriate for the specimen and method.

How do I prepare for the test?

Follow any preparation instructions included with your lab order. This test code does not specify a fasting requirement, so fast only if your healthcare professional or the laboratory tells you to do so.

Clinical interpretation

How abnormal results are interpreted and what conditions they suggest.

An abnormal cholestanol result may occur with disorders affecting cholesterol, bile-acid production, or liver function, including certain inherited metabolic diseases. The finding should be interpreted with symptoms, other laboratory results, and the specimen-specific reference information by your clinician.

Short name

Cholestanol test

Frequently asked questions

Is cholestanol the same as cholesterol?
No. Cholestanol is a related sterol that can be converted into bile acids, but it is distinct from cholesterol and is measured separately.
What does an abnormal result mean?
It may indicate an effect on cholesterol or bile-acid metabolism, but it does not identify a specific condition by itself. Your clinician will interpret it alongside the rest of your evaluation.
Do I need to fast before this test?
The test code does not specify fasting. Follow the instructions on your laboratory order, and ask the laboratory if you are unsure.
