I recently had some blood tests done to check for vasculitis, also one which the rheumatologist called a muscle test. he said he would check for poly mysotosis. I have received the results today but of course I only understand the ESR and CRP.I have a result with a star for Neutrophil Cytoplasmic antibody( AN with positive.P The normal result would be Negative, so does anyone know what that means? Myeloperoxidease(MPO) ANCA is<).02 and Proteinase 3 (PR3) ANCA0.2 I suppose these are not normal either. I am being treated with steroids and Benapali and wonder if I am on the right treatment.
