Liver Function Test (LFT)

500

The liver is one of the most important organs in the body. It’s important to measure the health and functioning of such a crucial organ. A liver function test helps assess exactly this by identifying a variety of conditions, such as liver damage, infections, and inflammation present here. 

People experiencing symptoms like yellowing of the skin or eyes (jaundice), abdominal pain, and persistent fatigue should get a liver function test, as these mainly occur when the livers inflamed or damaged.  LFT is also commonly recommended by doctors right before a person’s surgery for evaluation purposes. 

Based on the recommendation given by the doctor, a standard LFT typically comprises Alanine Aminotransferase (ALT/SGPT) and Aspartate Aminotransferase (AST/SGOT) to assess liver cell injury, Alkaline Phosphatase (ALP) and Gamma-Glutamyl Transferase (GGT) to evaluate bile duct function, and Total, Direct, and Indirect Bilirubin to detect jaundice and problems with bile metabolism. 

Oftentimes, a liver function test can help detect many conditions that, otherwise, can go undetected due to a person’s careless nature. With an LFT, people can help support their overall health by eliminating the presence of various diseases. Early detection helps doctors plan appropriate treatment for patients and significantly improves an individual’s recovery chances.
