IgE-bindingsassays (f.eks. radio- eller enzym-allergosorbent-assay (RAST eller EAST), enzymbundet immunosorbent-assay (ELISA) og elektroforese, efterfulgt af immunblotting med specifikke IgE-holdige sera) er egnede metoder.
IgE-binding assays (such as Radio or Enzyme Allergosorbent Assay (RAST or EAST), Enzyme Linked Immunosorbent Assay (ELISA) and electrophoresis followed by immunoblotting with specific IgE-containing sera) are adequate methods.
