Description

Order a peanut component blood test to detect an allergy to various proteins found in peanuts. This test measures the amount of allergen-specific antibodies in a blood sample. 

Over 13 allergenic components have been identified in peanuts. Of the 13 allergens, the most important markers are Ara h 1, 2, 3, 8, and 9.  All five of these allergens are tested in the peanut component blood test. Pinpointing sensitization to these five components can paint a clearer picture when determining allergic reactions.

Ara h 1, 2, and 3 sensitization indicate an individual is more likely to have a systemic reaction when eating peanuts. An Ara h 8 sensitization is generally associated with either no clinical reactivity or isolated local reactions, such as oral allergy. Like Ara h 1, 2, and 3, the protein Ara h 9 can cause extreme peanut reactions. However, most of the allergies to Ara h 9 are in southern Europe. Those with sensitivity to Ara h 9 may also react to pit-bearing fruits, such as cherries or peaches.

An allergy to peanuts triggers a reaction in an individual's immune system. The body views certain substances as toxic and produces IgE antibodies to these contaminants. These antibodies cause histamine to be released, which will cause the symptoms of an allergic reaction.

Allergy symptoms vary from one individual to the next ranging from mild to severe reactions, which can be experienced within minutes to hours after consumption.
