Liver Function Test (LFT)

The Liver Function Test (LFT) is a comprehensive group of blood tests used to evaluate the health and functioning of the liver. The liver performs essential functions such as metabolism, detoxification, protein synthesis, bile production, and nutrient storage. An LFT measures important liver enzymes, proteins, and other substances, including ALT (SGPT), AST (SGOT), Alkaline Phosphatase (ALP), Bilirubin, Total Protein, and Albumin, to assess liver function and detect liver-related disorders.

The Liver Function Test (LFT) is recommended for individuals with symptoms such as jaundice (yellowing of the skin or eyes), fatigue, abdominal pain or swelling, dark urine, pale-colored stools, nausea, loss of appetite, or those with a history of hepatitis, excessive alcohol consumption, fatty liver disease, or long-term medication use. Elevated liver enzymes may indicate liver inflammation or damage, increased bilirubin levels may suggest jaundice or bile flow obstruction, and low albumin levels can be associated with chronic liver disease. The LFT is also widely used to monitor patients with known liver disorders and evaluate the effectiveness of treatment. Test results should always be interpreted together with the patient’s symptoms, medical history, imaging studies, and other laboratory investigations for an accurate diagnosis and appropriate management. Early detection through LFT helps prevent serious liver complications and supports long-term liver health.
