What this test is

A liver function test (LFT) is a group of blood tests that measure specific enzymes, proteins, and other substances made by your liver. These tests help determine if your liver is damaged or not working properly.

What it measures

Albumin — a protein made by the liver that helps maintain fluid balance
Alkaline phosphatase (ALP) — an enzyme found in the liver and bone
Alanine aminotransferase (ALT) — an enzyme primarily found in the liver
Aspartate aminotransferase (AST) — an enzyme found in the liver, heart, and muscles
Bilirubin — a waste product processed by the liver
Total protein — measures the total amount of protein in the blood

What the test involves

This test requires a standard blood draw from a vein in your arm. A healthcare professional will collect the sample and send it to a laboratory for analysis.

Why it is often ordered

Clinicians often order liver function tests to screen for liver disease, monitor the progression of liver disease, and assess the effectiveness of treatment. They can also help detect liver damage caused by medications or other substances.

Preparation

Follow the specific instructions provided by the laboratory where you will have your blood drawn. Some tests may require fasting for a period before the sample is collected.

How results are reported

Your results will be reported by the laboratory, usually within a few business days. The laboratory will provide reference ranges, which are ranges of expected values, as these can vary between different labs.
