Eosinophilia is an unusually high number of eosinophils in your blood (≥ [greater than or equal to] 500 eosinophils per microliter). Eosinophils are one of several white blood cells that support your immune system.

Eosinophilia (e-o-sin-o-FILL-e-uh) is the presence of too many eosinophils in the body. An eosinophil is part of a group of cells called white blood cells. They are measured as part of a blood test called a complete blood count.

Eosinophilia is a condition in which the eosinophil count in the peripheral blood exceeds 5 × 10 8 /L (500/μL). [1] Hypereosinophilia is an elevation in an individual's circulating blood eosinophil count above 1.5 × 10 9 /L (i.e. 1,500/μL).

Eosinophilia is defined as a peripheral blood eosinophil count > 500/mcL (> 0.5 × 109/L). Causes and associated disorders are myriad but often represent an allergic reaction or a parasitic infection. Eosinophilia can be reactive (secondary) or the primary manifestation of a …

2024年7月7日 · Eosinophilia is an increased number of eosinophilic white blood cells. It is a sign of certain medical conditions, including allergies, asthma, infections, immune disorders, and some types of cancer. Eosinophilia can be associated with symptoms like …

2022年7月5日 · There are three types of white blood cells, all with various functions to help your immune system, including granulocytes, lymphocytes and monocytes. Eosinophils are one of three types of granulocytes, along with neutrophils and basophils. Eosinophils prevent foreign organisms from growing inside of host cells (parasites).

2024年8月12日 · Eosinophilia is a peripheral eosinophil count greater than the upper limit of normal range, usually around 0.50 x 10 9 /L. In many cases the cause is clear - eg, atopic disease. However, the differential diagnosis includes …
