Interpreting IgE results


Interpretations

  • If your total IgE level is increased, it usually indicates that you are suffering from one or more allergies. Sometimes, increased levels are also associated with parasitic infections. 
  • An elevated IgE indicates an allergic process but does not indicate what a person is allergic to. In general, the greater the number of things a person is allergic to, the higher is the IgE level.
