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.

The healthcare professional verifies your details and explains the blood collection procedure.
A vein, usually in the arm, is cleaned with an antiseptic solution.
A sterile needle is used to collect a small blood sample into the required collection tubes.
The blood sample is analysed for liver function parameters, which may include Alanine Aminotransferase (ALT/SGPT), Aspartate Aminotransferase (AST/SGOT), Alkaline Phosphatase (ALP), Gamma-Glutamyl Transferase (GGT), Total Bilirubin, Direct Bilirubin, Indirect Bilirubin, Total Protein, Albumin, and Globulin, depending on the prescribed test profile.
After the sample is collected, gentle pressure is applied to the puncture site, and a small bandage is placed.
The procedure is quick, safe, and usually completed within 5–10 minutes.
Reports are generally available within 24 hours*.
