eosinophils
Parasite-attacking white cells
Eosinophils are a type of white blood cell involved in the immune response, particularly against parasites and in allergic reactions.
They're named for their affinity for eosin, a red dye that stains them distinctively under microscopy.
Elevated eosinophil counts often indicate allergies, asthma, or parasitic infection: The blood work showed elevated eosinophils.
