 Information Source : Liver Specialist in Kochi

Liver blood tests, also known as liver function tests (LFTs), measure various substances in the blood to assess the health and function of the liver. Abnormal results in liver blood tests can indicate potential liver damage, inflammation, or other liver-related conditions. Here is a general overview of high, low, and normal results for common liver blood tests:




Alanine Aminotransferase (ALT):


High levels (elevated): Indicates possible liver damage, such as hepatitis or cirrhosis.

Low levels: Not typically significant.


Aspartate Aminotransferase (AST):


High levels (elevated): Can indicate liver damage or injury, but AST is also found in other organs like the heart and muscles.

Low levels: Not typically significant.


Alkaline phosphatase (ALP):


High levels (elevated): Can indicate liver or bile duct obstruction, liver disease, or bone disorders.

Low levels: Not typically significant.


Total bilirubin:


High levels (elevated): Can indicate liver dysfunction, blockage of the bile ducts, or excessive breakdown of red blood cells.

Low levels: Not typically significant.


Direct bilirubin:


High levels (elevated): Can indicate liver or bile duct problems, such as blockage or inflammation.

Low levels: Not typically significant.


Total protein:


High levels (elevated): Can be seen in chronic inflammation, infections, or certain cancers.

Low levels: Can indicate liver disease, malnutrition, or kidney problems.


Albumin:


High levels: Not typically significant.

Low levels (decreased): Can indicate liver disease, malnutrition, or kidney problems.


Gamma-glutamyl transferase (GGT):


High levels (elevated): Can indicate liver disease, alcohol abuse, or certain medications.

Low levels: Not typically significant.


It's important to note that these are general guidelines, and interpretation of liver blood test results should always be done by a healthcare professional. They will consider various factors such as medical history, symptoms, and other test results to provide a proper diagnosis and appropriate treatment if necessary.
