I would ask for a CBC w/ differential looking for high wbc and
high eosinophils. ANA (anti nuclear antibodies), for large amounts of circulating auto
immune disease, ANCA which is also for auto
antibodies linked to
Churg-Strauss(CSS), a esr and crp to
look for internal inflammation. Really he needs an entire auto
immune blood workup, which includes organ tests for specific organ involvement, which includes liver, and meto
bolic profiles. Most definitly a chest and sinus CT.
