Common Causes
The main causes leading to eosinophilia. Eosinopenia - a decrease in the content of eosinophils (less than 0.05 × 10 9 / l) - in most cases is due to an increase in adrenocorticoid activity, which leads to a delay in eosinophils in the bone marrow. Eosinopenia is especially characteristic for the initial phase of the infectious-toxic process.

What is the normal eosinophil count?
Normal levels — In peripheral blood, an absolute eosinophil count (determined by multiplying the total WBC count by the percentage of eosinophils) of 0 to 500 cells/microL (<0.5 x 10 9 /L) is typically considered normal. Defining the normal range by percentage of WBC can be problematic because differences in absolute neutrophil counts between ethnic groups can dramatically impact the percent of eosinophilia [ 3 ]. In addition, blood eosinophil counts have been reported to vary within the same person at different times of day and on different days, both in individuals with eosinophilic disorders and in healthy volunteers [ 4-6 ]. However, results are inconsistent among studies, and the variability in counts is rarely large enough to impact care.

What is the name of the disease where white blood cells build up in the lining of the mouth?
Eosinophilic esophagitis (e-o-sin-o-FILL-ik uh-sof-uh-JIE-tis) is a chronic immune system disease in which a type of white blood cell (eosinophil) builds up in the lining of the tube that connects your mouth to your stomach (esophagus). This buildup, which is a reaction to foods, allergens or acid reflux, can inflame or injure the esophageal tissue. Damaged esophageal tissue can lead to difficulty swallowing or cause food to get stuck when you swallow.
