Had CBC. Eosinophils Abnormal. Are They Elevated?

I recently had a physical, including a CBC. Everything was in the normal range ( WBC , RBC , Hemoglobin , Lymphocytes, etc.) except for my Eosinophils. Mine were 17 (range from 0-5) and my EOS was 1.4 (range from 0.0-0.7). I m going back to my doctor in 2 weeks to do another CBC to see if they are still elevated. What could be the cause of this?

Thanks for your query.
An eosinophil is a type of white blood cell.
Eosinophils are produced in the bone marrow and are normally found in the bloodstream and the gut lining.
Common causes of high eosinophil counts are parasitic infections,asthma,hay fever & allergies to drugs & food. Though the list of causes is exhaustive it is good idea to repeat the counts after 2-3 weeks before proceeding for further work up.

Hi wclonin

peripheral eosinophilia ha several cause. I wish you must have added your symptomatology.

usual causes are, Total peripheral eosinophilia(TPE) due to filariasis, loeffler's syndrome ( due to passage of worms like ascariasis through lungs), allergic phenomenon, ABPA ( asthma complicated by mould aspergillus), hypereosinophilic syndrome (when no cause is detected and absolute eosinophil count is persistently above 1500 for 6 months), churgh strauss syndrome ( a vasculitis which involves the small vessels of the body) etc....

hope you will have your diagnosis made when you meet your doctor

best wishes
