magent

Wai 2003 AST to platelet ratio index (APRI) from AST, laboratory AST ULN, and platelet count. Returns APRI to two decimals plus published training-set cut-offs for significant fibrosis (Ishak ≥3) and cirrhosis. ULN is required; magent does not assume 40 U/L. Not a diagnosis, not FIB-4, and not a biopsy.
