LFT Interpreter

Enter lab values below to get real-time interpretation using the BAAGAP method. Follow the systematic approach: Bilirubin → ALT → AST → GGT → ALP → Protein.

Unit System

mg/dL, U/L, g/dL

Bilirubin

Question: What type of jaundice?

Interpretation: Decide conjugated vs unconjugated hyperbilirubinemia

Step 1: Bilirubin — Type of Jaundice

Total Bilirubin

mg/dL

Normal: 0.2 – 1.2 mg/dL

Direct Bilirubin

mg/dL

Normal: 0 – 0.3 mg/dL

Indirect Bilirubin

mg/dL

Normal: 0.1 – 0.9 mg/dL

Step 2: ALT & AST — Liver Cell Injury

ALT (SGPT)

U/L

Normal: 7 – 56 U/L

AST (SGOT)

U/L

Normal: 8 – 40 U/L

Step 3: ALP & GGT — Obstruction?

Alkaline Phosphatase

U/L

Normal: 44 – 147 U/L

Gamma-Glutamyl Transferase

U/L

Normal: 9 – 48 U/L

Step 4: Albumin & Protein — Chronic Status

Albumin

g/dL

Normal: 3.5 – 5 g/dL

Total Protein

g/dL

Normal: 6.4 – 8.3 g/dL

Globulin

g/dL

Normal: 2 – 3.5 g/dL

Pattern Detection

Enter lab values to detect patterns. The system will identify hepatocellular, obstructive, or chronic liver disease patterns.

Key Rule

Start with Bilirubin, Check Enzymes, Confirm Source, Assess Chronic Status

Where People Go Wrong

✗ Check only Bilirubin
✗ Ignore Enzyme Pattern
✗ Skip GGT
✗ Ignore Albumin (Chronic Marker)
