Liver Function Test (LFT) Overview

What is the Liver Function Test (LFT)?

The Liver Function Test (LFT) is a group of blood tests that evaluate the health of your liver by measuring levels of liver enzymes, bilirubin, and proteins. The liver plays a key role in detoxification, digestion, and metabolism, so monitoring its function is crucial for overall health.

Abnormal results can indicate liver conditions such as hepatitis, fatty liver disease, cirrhosis, or bile duct obstruction. High liver enzyme levels may signal liver inflammation or damage, while abnormal bilirubin or protein levels can reflect impaired liver processing or synthesis.

This test is useful for people with symptoms such as fatigue, jaundice (yellowing of the skin or eyes), dark urine, abdominal pain, or unexplained digestive issues. It is also commonly used for routine health checkups, monitoring chronic liver conditions, or assessing the effects of medications on the liver. Early detection of liver function abnormalities allows timely medical intervention and lifestyle adjustments to prevent further complications.

Why Take the Liver Function Test (LFT)?

This test is recommended if you:

• Have symptoms of liver disease such as jaundice, abdominal discomfort, or fatigue

• Are at risk of hepatitis, fatty liver, or other chronic liver conditions

• Are taking medications or supplements that can affect liver function

• Require pre-surgical evaluation or routine health screening

• Want to monitor liver health in case of chronic illnesses or metabolic disorders

How is the Liver Function Test (LFT) Carried Out?

• A small blood sample is drawn from your arm.

• The sample is processed in a lab to measure liver enzymes, bilirubin, and protein levels.
