I was told that I have a high eosinophil count (1900).  The doctor has checked for parasites (none found) and now wants to do a bone marrow biopsy.  I do have Raynauds and wondered if the high eosinophils could be because of some sort of auto immune issue.  How would they check for auto immune?  They want to do the bone marrow biopsy to test for HES
Hello, I understand your concern. I am Chat Doctor, infectious disease specialist, answering your concern. The two most common cause of high eosinophil count is allergy and parasitic infections. As you have ruled out parasites the remaining one is allergy. I suspect allergy in you. Check out for allergy and allergen. Once you are out of allergen your eosinophil count can come down. Glad to answer your further concern contact me on bit.ly/ Chat Doctor.  Thank you, ChatDoctor
