Liver function tests:

What does a liver function test include?

It measures the different enzymes, proteins and other substances produced by the liver. These checks indicate the health of your liver. Different substances are tested by taking a single blood sample and they include:


It is one of the proteins produced by the liver. Your body requires proteins to fight infections and for other functions. Low albumin and total protein levels might indicate a liver disease.

Different enzymes produced by the liver:

  • Alanine transaminase (ALT) –

It is an enzyme in the liver that converts proteins into energy. In case the liver gets damaged, ALT releases into the bloodstream and the level increases.

  • Gamma-glutamyltransferase (GGT) –

It is an enzyme found in the blood. If the levels are higher than normal it indicates liver or bile duct damage.

  • Aspartate transaminase (AST) –

AST helps to metabolize amino acids and it is usually present in the blood at low levels. If the AST levels rise it might be due to liver damage, disease or muscle damage.

  • Alkaline phosphatase (ALP) –

ALP is an enzyme in the liver and bone. It contributes significantly to break down proteins. If the ALP is high, it indicates liver damage or disease like blocked bile duct or particular bone diseases.

  • L-lactate dehydrogenase (LD) –

It is an enzyme in the liver. High levels indicate liver damage or any other disorder. This is an enzyme found in most body cells. LD gets released in the blood when cells are damaged due to some injury or disease.

If any of these levels are outside the normal range it might indicate a liver disease.

Total protein:

It is the total amount of proteins in the blood.

Prothrombin time:

A protein that is part of the blood clotting. Increased levels of PT indicate liver damage or the reason could be blood thinning drugs.


It is the waste product made by the liver. It is a substance produced during breakdown of red blood cells. Bilirubin passes through liver and excreted in stools. High bilirubin might lead to liver damage or disease or some type of anemia.
