AAAAI support of the EAACI Position Paper on IgG4.

摘要

The recent European Academy of Allergy and Clinical Immunology (EAACI) Position Paper by Stapel et al1 concerning testing for IgG4 against foods is a timely reminder that this issue is pervasive throughout the world. The ease of obtaining laboratory tests for suspected allergic symptoms, which then need sophisticated interpretation, is an ongoing problem. It should be stressed that the use of all tests for allergy should be supported by the scientific evidence base, when it exists. The improper use of certain tests to make diagnoses, in the absence of supporting clinical evidence, can lead to poor patient care and can have a serious adverse impact on patient quality of life.
