How this service works
Alvarez 1999 revised original IAIHG AIH score, not Hennes 2008 simplified. Caller-assigned sex, ALP:AST/ALT ratio, globulin/IgG, ANA/SMA/LKM titer, AMA, viral markers, drugs, alcohol, additive histology, other autoimmune disease; optional HLA/other autoantibodies if seronegative and treatment response. Pretreatment definite >15 / probable 10-15; posttreatment definite >17 / probable 12-17. magent does not read histology. Not a diagnosis or immunosuppression order.
Output
Returns a numeric AIH score computed from all weighted input parameters, along with interpretation of that score against the Alvarez 1999 pretreatment thresholds (definite >15, probable 10–15) and posttreatment thresholds (definite >17, probable 12–17). Does not provide a diagnosis or treatment recommendation.
Example use cases
Pretreatment AIH workup staging
“I have a female patient with ALP:AST ratio under 1.5x ULN, IgG at 1.5–2x ULN, ANA titer at 1:80, AMA negative, no viral markers, no hepatotoxic drugs, alcohol under 25 g/day, interface hepatitis present, lymphoplasmacytic infiltrate present, liver cell rosettes present, no biliary changes, no other atypical histology, and no other autoimmune disease — run the original Alvarez 1999 AIH score and tell me if she meets definite or probable criteria pretreatment.”
Posttreatment AIH response confirmation
“After treatment, a male patient has ALP:AST ratio under 1.5x ULN, IgG now at 1–1.5x ULN, SMA titer 1:40, AMA negative, no viral markers, no drug or alcohol concerns, interface hepatitis still present, lymphoplasmacytic infiltrate present, no rosettes, no biliary changes, no other atypical histology, and he has another autoimmune disease — compute the original IAIHG AIH score and check whether posttreatment definite criteria are met.”
Seronegative AIH with HLA tiebreaker
“I need the Alvarez 1999 AIH score for a female patient who is seronegative (autoantibody titer below 1:40), ALP:AST ratio under 1.5x ULN, IgG over 2x ULN, AMA negative, no viral markers, no hepatotoxic drugs, alcohol under 25 g/day, interface hepatitis present, lymphoplasmacytic infiltrate present, liver cell rosettes present, no biliary changes, no atypical histology, no other autoimmune disease — and she is HLA DR4 positive, so include that in the score.”

Endpoint
GEThttps://api.magentlab.com/api/calc/aih_originalWhen to prefer
Use this endpoint when you need the full 1999 Alvarez revised original IAIHG AIH scoring system rather than the simpler 2008 Hennes simplified score. Prefer it when histology data is available and you want granular multi-component scoring including HLA, treatment response thresholds, and additive histology sub-components. Not appropriate as a standalone diagnosis or to replace clinical judgment.
Side effects
- Missing required query parameters (sex, alp_ratio, globulin_igg, autoantibody_titer, ama_positive, viral_markers_positive, hepatotoxic_drugs, alcohol_intake, histology fields, other_autoimmune_disease) returns a 400 error
- Invalid enum values for categorical parameters return validation errors
- HLA parameter ignored unless autoantibody_titer is lt_1_40 (seronegative), so passing it in non-seronegative contexts has no scoring effect
- Payment failure or missing x402 header causes payment-required rejection
