Hello and hope you are doing well.
With an increased eosinophil count it is only possible to say that you have allergies, but it is not possible to say what allergies. Consult an allergy specialist. First he may do a blood IgE levels to see if they are raised. Next, he will do skin testing. This test is painless, in which a very small amount of certain allergens are pricked into the surface of your skin. If you have allergies, just a little swelling will occur where the allergen was introduced. Reactions occur within about 15 minutes. If needed more sensitive intradermal tests will be used in which a small amount of allergen is injected within the skin. Based on this he may plan for immunotherapy.
Hope this helped and do keep us posted.
