Skin prick test

Skin prick test

A test of IgE-related allergy involving pricking through the suspect allergen into the epidermis of the skin and observing for an immediate hypersensitivity response. This includes: itching, erythema, weal and flare response. It is a diagnostic tool but it is essential to have resuscitation facilities and adrenaline to hand in case of a serious anaphylactic reaction.

Avoid in patients with the following:
* On anti-histamines (false negative result)
* Previous history of anaphylaxis (more dangerous)
* Extensive skin disease (practical problem)
* Presence of dermatographism (false positive result)
* Very young, pregnant women (relative)
