Allergy, skin prick testing

Analysis of the value to allergists of skin testing from papers published between 1970 and 2005 concludes that; when preformed and evaluated correctly, skin testing is the most effective diagnostic tool available for the confirmation of allergic disease.
The test, however must be combined with a physical exam and notations of the patient's medical history and social environment in order to give a sound basis for managing allergies and allergic disease.

The paper includes a clinical form and stepped procedure for clinical technicians on how best to record and evaluate skin tests. As house dust mites are known to be the major cause of allergy, worldwide, and the environment in which they thrive encourages moulds, and other allergy triggers, early skin prick testing, especially for children, is recommended.

There are some patients however who can skin prick test positive for a specific allergen but have no clinical symptoms to that trigger. They would be considered allergen 'tolerant' to the trigger and avoidance advice may not be appropriate. On the other hand, there are a few patients who may be at risk of a serious allergic reaction to a trigger but demonstrate no outward reaction in common allergy testing. In all cases, allergy testing needs be a clinical procedure by trained clinicians.
