Hi there and thank you for the question. I am a Registered Nurse and will be happy to help you today.
If you have always had eczema and allergies (allergic rhinitis), this could be in response to a flare up of it....higher than normal levels of eosinophils are related to skin conditions, asthma, even allergies to drugs. You could see an allergy Dr to help you get your eczema under control, but I don't think you'll have to do allergy testing again unless you just want it done. However, a new allergy Dr may want to know if you have developed any new allergies, so that is up to you so since you don't want it, you can tell them that you've had them before and don't want to repeat it. I would keep a check on the eosinophils and try to get the eczema under control so the count will come down. Reply back if I can help you further or if you have any other questions.
