Simplified autoimmune-hepatitis criteria (IAIHG 2008): autoantibodies + IgG + histology + absence of viral hepatitis, 0-8; >= 6 probable, >= 7 definite.

Example
- Autoantibodies
- 2
- IgG
- 1
- Liver histology
- 2
- Absence of viral hepatitis
- Yes
Result: Simplified AIH score 6 of 8 — probable AIH (>= 6).
The tool opens with these values already filled in. Replace them with your own.
What the result means
- < 6
- AIH not met.
- >= 6
- Probable AIH.
- >= 7
- Definite AIH (autoantibodies + IgG + histology + viral-absent, 0-8). A criteria score, not a standalone diagnosis.
What you enter
- Autoantibodies (ANA/SMA/anti-LKM1/SLA)
- IgG
- Liver histology
- Absence of viral hepatitis
