An allergic reaction in the body can increase the percentage
of Eosinophils that is present in the blood. Any normal human blood contains
about 1% to 2% of the total number of White Blood Corpuscles (WBC). During an allergy
the percentage can go to as high as 20% to 30% of WBC present. Eosinophils are
actually specialized type of blood cells that react by increasing during any
allergic reactions in the body. Eosinophils also increase during any parasitic
infection in the stomach.
