LIVER FUNCTION TESTS - LFT

Liver Function Tests (LFT)

The Liver Function Tests (LFT) is a comprehensive blood test panel used to assess the overall health and functioning of the liver. It measures important liver enzymes, proteins, and bilirubin levels, helping doctors diagnose liver diseases, infections, inflammation, bile duct disorders, and monitor ongoing treatment effectiveness.

The liver performs essential body functions such as detoxification, metabolism, digestion support, protein production, and nutrient storage. Any damage or dysfunction can significantly affect overall health. The LFT helps detect early liver abnormalities before symptoms become severe.

A standard LFT panel commonly includes:

• SGOT (AST)
• SGPT (ALT)
• Alkaline Phosphatase (ALP)
• Total Bilirubin
• Direct Bilirubin
• Indirect Bilirubin
• Total Protein
• Albumin
• Globulin
• A/G Ratio

These parameters provide detailed insight into liver cell damage, bile flow obstruction, protein production, and liver metabolic function.

Benefits of the Test

• Detects liver disease early
• Monitors liver damage and inflammation
• Assesses bile duct function
• Evaluates jaundice causes
• Monitors medication-related liver effects
• Helps assess alcohol-related liver injury

• Yellowing of skin or eyes (jaundice)
• Abdominal pain or swelling
