<s>[INST] Hi I just had reults in from blood type my EOS level was a 9 . I asked my cardio doctor about this and he said hay fever could cause high counts {which I have} WBC count and RBC count are all normal as is everyhing else in my bllod panel, Should I not be concerned it was normal back in february of this year?? My E-mail is YYYY@YYYY thank you [/INST] Hi,Thanks for asking.Based on your query, my opinion is as follows.1. Eosinophil count is mildly increased.2. Any dust, allergy to food or pollution could have caused it. Specifically, if it were to be more than 15, it would be worrisome.3. At present, not to worry. All counts are normal. Avoid exposure to dusty environment.Hope it helps.Any further queries, happy to help again </s>
