History or current clinically significant immune disorders including autoimmune disease (e.g., systemic lupus erythematosus (SLE), autoimmune hemolytic anemia, autoimmune liver disease) or a history of any blood dyscrasia. Thus a history of anemias or cytopenias that were not obviously related to a limited benign process (e.g., anemia related to menstrual bleeding) will be reason for exclusion. Consultation with hematology will be used for help with any 'gray area' cases.
