28% Eosinophils Why so high in child? Range=0-4%?

Question

My 9 year old son has had two separate blood tests. The first resulted in low lymphs, high basophils and very high eosinophils (14%). We waited three weeks and repeated the test. Now the test shows 28% Eosinophils and elevated AST (47). Doctor has ruled out parasites via a stool sample. It was negative. He has no history of allergies. What could be wrong with my little guy?

Answer 1

Elevated eosinophils can occur in so many situations.Please have a blood cell maturation study and have the count repeated on frequent occasions
