"While the presence of an increased AEC in a refugee is highly suggestive of current or recent infection with a tissue-invasive parasite, the absence of eosinophilia does not indicate lack of parasitic infection [1, 2]. Not all parasitic infections cause eosinophilia. For example, the human host does not always mount an eosinophilic response to tissue-invasive parasites. Non-tissue invasive parasites such as protozoa (e.g. giardia and ameba) do not normally illicit an eosinophilic response." -http://refugeehealthta.org/physical-mental-health/health-conditions/infectious-diseases/parasites/eosinophilia/
Also I wouldn't waste too much time with medical idiots personally. Keep in mind you can order a variety of parasite meds online if you think you know what you are fighting. Good luck.
