The Indoor Allergen sIgE FIA Test is a fluorescence immunoassay that is used with the FIAflex™ Fluorescent Immunoassay Analyzer for the qualitative detection of allergen-specific IgE antibodies against mould mix, Der. pteronyssinus/Der. farinae and house dust in human serum or plasma specimens. It is used for assistant diagnosis of type I hypersensitivity reactions and related symptoms mediated by allergen-specific IgE antibodies.
