Online Liver Function Test (LFT Test) in Connecticut
Online Liver Function Test (LFT Test) can be ordered without a referral, and this guide covers what to expect. This panel of tests helps evaluate how well your liver is functioning and provides an overall assessment of liver health.
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.
