For this purpose, the seroprevalence of toxocariasis and anisakiasis in individuals with urticaria was measured through the presence of specific IgG (sIgG) and IgE (sIgE) antibodies against crude and isolated antigens/allergens using molecular diagnostic methods concretely Component-resolved diagnosis (CRD) [28] in comparison to that in individuals without urticaria, including healthy general population and atopic patients. The gene discussed is IGHE; the disease is toxocariasis.
