The LFT Test or Liver Function Test is a blood test used to evaluate the health of the liver by measuring various enzymes, proteins, and substances in the blood. It helps detect liver diseases, infections, inflammation, and overall liver function. The test typically includes markers such as Alanine Aminotransferase (ALT), Aspartate Aminotransferase (AST), Alkaline Phosphatase (ALP), Bilirubin, Albumin, and Total Protein Levels. Doctors recommend an LFT Test for individuals experiencing symptoms like jaundice (yellowing of the skin and eyes), fatigue, abdominal pain, nausea, or unexplained weight loss. It is also advised for people with alcohol-related liver damage, hepatitis infections, fatty liver disease, or those taking medications that may affect liver function. A simple blood sample is required for the test, and fasting for 8-12 hours before the test may be recommended for accurate results. If abnormalities are detected, lifestyle modifications, dietary changes, and medications may be suggested to improve liver health. Early detection through an LFT Test helps prevent severe liver complications and ensures timely medical intervention.
