Is eosinophilia serious?

Depending on your eosinophil count, eosinophilia can be mild, moderate or severe. High eosinophil levels can indicate a mild condition such as a drug reaction or allergy, or a severe condition could cause it, including some blood disorders. Sometimes, high numbers of eosinophils crowd together at specific areas of your body, causing medical conditions linked to inflammation that can affect multiple areas of your body.
