CORE LABORATORY
This patient had an increased WBC count as a consequence of eosinophilia. There were no other hematological abnormalities. The GRANULARITY/ LOBULARITY plot demonstrated the clear separation of eosinophils and neutrophils using the polarized and depolarized 90° scatter.
Eosinophilia of this magnitude is well compatible with severe allergy, parasitic infections or with eosinophilic malignancies.
Eosinophilia, greater than 450 to 500 eosinophils/μL in peripheral blood, is a hallmark of or a related finding in many allergic, infectious, autoimmune, idiopathic, malignant, and miscellaneous clinical scenarios. The clinical history is often the most important clue in discovering a pathway by which the patient is possibly affected by eosinophilia. Tailored evaluation based on scenario, including allergy testing, laboratory testing, imaging, and pathologic biopsy of affected areas can be useful in confirming a diagnosis.
