Recent research has raised concerns about the validity of results of skin prick tests or Immunoglobulin tests carried out on their own. Some important findings have been missed.
Tests were carried out on a group of 40 children aged under 4 years old who had a family history of asthma and/or eczema, as well as recurrent wheezing. They underwent skin prick tests as well as IgE blood tests and the results showed that one or more allergens were missed in 80% of children if only skin prick tests were performed, and in 38% of the children one or more allergens was missed if they had only IgE testing.
These discrepancies indicate that both forms of testing would be more appropriate to identify the allergens and define the appropriate form of treatment and/or desensitisation for young children.
The results of this study is published in the Annals of Allergy, Asthma and Immunology.
