Our Progenitor Eosinophil Immunophenotyping Panel (PEIP) identifies and semi-quantitates the eosinophil progenitor cells in the peripheral blood. In patients with eosinophilic derived inflammatory diseases, it is thought that eosinophils originating from hematopoietic stem cells located in the bone marrow are mobilized to sites of inflammation. It is at these peripheral sites of inflammation where the eosinophilic progenitor (EOP) cells differentiate and proliferate. PEIP offers your patients a minimally-invasive alternative to monitoring disease activity.
