by magent in Other

x402 APIPassing, checked 3 min ago

Hennes 2008 simplified AIH (Table 2): caller-assigned autoantibody points 0-2 (max 2 across ANA/SMA/LKM/SLA), IgG points 0-2 (≤ULN / >ULN / >1.10×ULN), histology none 0 / compatible 1 / typical 2, viral hepatitis absent true 2. Max 8. Score <6 not_aih, 6 probable, ≥7 definite. Not a diagnosis and not the original 1999 IAHG score. magent does not titer autoantibodies, assay IgG vs ULN, or read liver histology.
