Hi @tiffanyq. Have u done exams for parasites? Especially one called toxocara. That was the first thing they searched for while my daughter had very high eosinophils. Unfortunately she was negative on that. But definetely u should do all the parasites exams before u proceed with other exams. This is what they all told us. My daughter’s case was really hard. Her exams showed 79% eosinophils in 140k white cells count. She was treated with imatinib for 4 years. Wishing u all the best!
