Eosinophils are a type of white blood cell involved in allergic reactions and parasitic infections. High levels of eosinophils can indicate these conditions.

iollo markers that associate with Eosinophils

Arachidonic acid

Arachidonic acid is converted to inflammatory leukotrienes that activate and attract eosinophils. Elevated arachidonic acid may indicate increased eosinophil-mediated inflammation.


Histamine released by mast cells and basophils can activate eosinophils and increase their levels. Elevated histamine may suggest an allergic response involving eosinophils.
