What are Liver Function Tests (LFTs)?
Liver function tests or LFTs are a blood test that measures the levels of various enzymes and proteins in the blood that indicate the health of the liver. Doctors perform this test to diagnose liver diseases, including hepatitis and cirrhosis.

LFTs are performed to diagnose liver diseases, monitor the progression of liver diseases, and to check the liver function before prescribing medications that may be harmful to the liver.
Types of Liver Function Tests
There are many different types of liver function tests. Some of the most common LFTs include alanine transaminase (ALT), aspartate transaminase (AST), alkaline phosphatase (ALP), gamma-glutamyl transferase (GGT), and bilirubin.
Interpreting Liver Function Test Results
The interpretation of liver function test results varies from person to person, depending on their age, sex, and medical history. However, elevated levels of enzymes like ALT, AST, and GGT in the blood are an indication of liver damage.
Factors that Affect LFT Results
Several factors can affect liver function test results, including alcohol consumption, medications, and other medical conditions like diabetes.
