Routine laboratory tests of blood were normal (white blood count 7400/mmc, hemoglobin 13.8 g/dL, platelts 254,000, polymerase chain reaction negative), no evidence of eosinophilia (190/L, normal value 30–510, 2.6%), IgE 7.24 kU/L (normal value < 100). Here, IGHE is linked to Increased total eosinophil count.
