About this test
A Liver Function Test (LFT) measures SGPT (ALT), SGOT (AST), bilirubin, alkaline phosphatase, total protein and albumin to assess how well your liver is working. It helps detect fatty liver, hepatitis, alcohol-related damage, bile-duct problems and the effect of medicines on the liver.
Clinical significance
Raised SGPT/SGOT point to liver-cell injury (fatty liver, hepatitis, alcohol or drug effects), while high bilirubin and alkaline phosphatase suggest jaundice or bile-flow obstruction. Low albumin can indicate long-standing liver disease. The pattern of abnormality helps your doctor pinpoint the cause and track treatment.
