Eosinophilia

Eosinophilia is the state of having too many eosinophils in the blood.

Eosinophils are increased in parasitic infections, allergic disorders and in some drug reactions.

They are also produced in excess in some forms of chronic myeloid leukaemia[?].

The release of interleukin[?]-5 by T cells, mast cells and macrophages stimulates the production of eosinophils.
