Allergen, Food, Pea
Also known as: PEA
Use
The Allergen, Food, Pea test identifies IgE antibodies specific to pea allergen, which may help in diagnosing allergic conditions. The quantitative results aid in assessing the likelihood of an IgE mediated allergic reaction; however, clinical correlation is necessary as the allergen-specific IgE levels do not always correlate with clinical symptoms or the results of skin testing. A comprehensive evaluation including clinical history and in vivo testing is essential, as a negative test cannot entirely rule out an allergy or potential for anaphylaxis.
Special Instructions
Not provided.
Limitations
Results between 0.10-0.34 kU/L have uncertain clinical relevance and are intended for specialist use. Despite higher allergen-specific IgE concentrations indicating increased allergen exposure, these levels may not directly measure clinical reactions or parallel outcomes from common allergy tests like skin prick tests. A negative result does not exclude the potential for clinical allergy or anaphylactic incidents.
