Allergic diseases? What reason is eosinophil on the high side

summary

How is eosinophil percentage on the high side to return a responsibility? Eosinophils accounted for 0.5% ~ 5% of the total number of leukocytes, and the absolute value was 0.05 ~ 0.50 × 10 ^ 9 / L. Many people in the physical examination found that the percentage of eosinophils is high. So what is the reason for the high percentage of eosinophils? Let's take a look at the following introduction.

Allergic diseases? What reason is eosinophil on the high side

First: allergic diseases: bronchial asthma, drug allergy, urticaria, food allergy, angioneurotic edema, serum diseases and other peripheral blood eosinophils increased by more than 10%.

Second: parasitic diseases: schistosomiasis, ascariasis, hookworm and other blood eosinophils increased, often up to 10% or more. The number of eosinophils increased significantly in some patients with parasitic infection, and the total number of inverted leukocytes reached tens of thousands. More than 90% of them were eosinophils, which were eosinophilic leukemoid reaction.

Third: skin diseases: such as eczema, exfoliative dermatitis, pemphigus, psoriasis, etc. can be seen in peripheral blood eosinophils mild to moderate increase.

matters needing attention

For example, chronic myeloid leukemia, eosinophilic leukemia, lymphoma, multiple myeloma, eosinophilic granuloma and so on, peripheral blood eosinophils can be increased to varying degrees, and some can be accompanied by infantile eosinophilia.
