What to Expect from a Liver Function Test for Fatty Liver Disease

The panel may include enzymes linked with liver-cell irritation, bilirubin, albumin, and clotting-related measurements. Fatty liver can occur with normal or abnormal results, so clinicians often consider the full pattern rather than one number. They may also review weight changes, diabetes risk, cholesterol, medicines, alcohol intake, and symptoms. Imaging, such as an ultrasound, or another assessment may be needed to look for fat or signs of scarring. An abnormal result can have causes unrelated to fatty liver.

Check whether fasting is required and bring a list of prescriptions, supplements, and herbal products. Do not discontinue medicines unless the requesting clinician tells you to. The sample is collected from a vein; press firmly on the site afterward if it bleeds or bruises. At follow-up, discuss eating patterns, activity, alcohol, blood sugar, and cholesterol in a practical way. The plan may include repeat blood testing or imaging, depending on the result and your other health findings.

Seek urgent care for yellow eyes or skin, vomiting blood, black stools, severe or rapidly increasing abdominal swelling, severe confusion, or fainting. Do not wait for routine blood-test results when these symptoms occur. For background on the procedure, see [Liver Function Test](/treatments/diagnostics-and-screening/liver-function-test/).

Ask whether the pattern suggests liver irritation, reduced liver function, or another cause. Clarify whether you need an ultrasound, a fibrosis assessment, repeat testing, or checks of blood sugar and cholesterol, and ask which changes are realistic for you.
