Peanut (f13) - High levels of peanut IgE can predict the likelihood of peanut sensitivity, but may not be solely predictive of reactions or allergic response.
PEANUT COMPONENTS:
Ara h 8 (f352) - LOW RISK of systemic reaction; Risk of mild, localized symptoms, such as itching/tingling of the lips, mouth, and oropharynx; cross-reactive with pollens (e.g., birch)
Ara h 9 (f427) - VARIABLE RISK of systemic reaction including anaphylaxis; often accompanied by sensitization to other peanut proteins; cross-reactive with fruits with pits (e.g., peaches)
Ara h 1, 2, 3 (f421, f423, f424) - HIGH RISK of systemic reaction including anaphylaxis; sensitization to Ara h 2 is nearly always associated with clinical peanut allergy
Components:
  • 80311 - ARA H 1
  • 80312 - ARA H 2
  • 80313 - ARA H 3
  • 80019 - ARA H 6
  • 80314 - ARA H 8 PR-10
  • 80315 - ARA H 9 LTP
