🧪 Liver Function Test (LFT) – Overview

A Liver Function Test (LFT) is a blood test panel that checks how well your liver is working by measuring enzymes, proteins, and bilirubin levels.

✅ Key Components of LFT

1. SGPT (ALT – Alanine Aminotransferase)

• Normal Range: 7–56 U/L

• Elevated in hepatitis, fatty liver, or alcohol damage

2. SGOT (AST – Aspartate Aminotransferase)

• Normal Range: 5–40 U/L

• Also found in heart and muscles, not liver-specific alone

3. Alkaline Phosphatase (ALP)

• Normal Range: 44–147 IU/L

• Raised in bile duct obstruction, bone disease

4. Gamma-Glutamyl Transferase (GGT)

• Detects alcohol-related or bile duct liver problems

5. Total Bilirubin (Direct + Indirect)

• Normal Range: 0.1–1.2 mg/dL

• High in jaundice, hepatitis, liver failure

6. Total Protein

• Checks overall protein levels made by the liver

7. Albumin

• Major protein made by the liver; low in liver or kidney disease

8. Globulin

• Other blood proteins, often measured with albumin

9. A/G Ratio (Albumin/Globulin Ratio)

• Helps assess liver synthetic function

🔍 Who Should Get LFT Done?
