ICC 2022 prefibrotic and overt PMF (Arber 2022)
ICC 2022 prefibrotic and overt PMF (Arber 2022). Diagnosed iff 3 majors and ≥1 minor. Majors: megakaryocyte morphology, not another myeloid neoplasm, JAK2/CALR/MPL or other clone or no reactive fibrosis. Minors: anemia not from comorbidity, WBC ≥11e9/L, splenomegaly, LDH above ULN; leukoerythroblastosis counts only in overt PMF. Not DIPSS, MIPSS70, WHO 5th, or post-PV/post-ET MF. magent does not read fibrosis grade or sequence drivers. Not a diagnosis or medical device.
Paid test badge: not yet. The checks above are free: we call the tool without paying and read the payment request it sends back. The Verified badge needs paid calls whose answers match the promised output, and nobody can buy a badge.
