Skin prick test method

If skin prick testing elicits no reaction, intra-dermal testing is usually employed. The latter

The usual diagnostic methods, both skin tests and specific IgE with whole Anisakis extract, have a good sensitivity but a low specificity to such a degree that in 22% of blood donors specific IgE to the parasite is detected [40] and at least 20% of patients with acute urticaria have positive skin prick tests with whole Anisakis extract [41 ]. As for BAT with whole Anisakis extract, Gonzalez-Munoz et al. [42] report a sensitivity of 96% with a specificity of 96%, which are clearly higher values than those from specific IgE.

In clinical diagnosis of sensitivity to allergens in food, the two methods used most frequently are the skin prick test (SPT) and the radioallergosorbent test (RAST). These tests have been used reliably for the diagnosis of allergy to peas, codfish, peanuts, egg white, wheat and wheat flour but were only partly reliable in detecting allergy to cow s milk, sardines, and white bea ns ( ).

Prick skin tests are used to screen patients with suspected IgE-mediated food allergies. In Table 3.3.5, there is a list of clinical conditions in which the methods of IgE detection are indicated (Chapman et al., 2006).
