LFTs Liver Tests Overview

 Liver Functions Tests (LFTs) Summary

LFTs stands for Liver Function Tests. These are a group of blood tests that are used to assess the health and function of the liver. LFTs provide information about the levels of various enzymes, proteins, and other substances in the blood that are produced or affected by the liver.

Common liver function tests include:

1. Alanine aminotransferase (ALT): ALT is an enzyme found predominantly in the liver. Elevated levels of ALT in the blood may indicate liver damage or inflammation.

2. Aspartate aminotransferase (AST): AST is an enzyme found in various tissues, including the liver. Increased levels of AST may suggest liver injury, although it is also found in other organs such as the heart and muscles.

3. Alkaline phosphatase (ALP): ALP is an enzyme found in various tissues, including the liver and bones. Elevated ALP levels may indicate liver or bone disorders.

4. Gamma-glutamyl transferase (GGT): GGT is an enzyme found in the liver and bile ducts. Increased GGT levels can be a sign of liver disease or alcohol abuse.

5. Bilirubin: Bilirubin is a yellow pigment produced during the breakdown of red blood cells. Elevated levels of bilirubin can be a sign of liver dysfunction or other conditions affecting the bile ducts.

6. Albumin: Albumin is a protein synthesized by the liver. Low levels of albumin may indicate liver disease or malnutrition.

7. Prothrombin time (PT): PT measures the time it takes for blood to clot. Abnormal PT can indicate liver damage or impaired production of clotting factors.

These are just a few examples of the tests that may be included in liver function tests. The interpretation of LFT results should be done by a healthcare professional who can consider the individual's medical history, symptoms, and other factors to make an accurate diagnosis.
