Advances in the Identification of Peanut Allergies!
  • Peanut allergies have increased 18% from 1997-2007.
  • The common laboratory skin and peanut specific IgE have a high sensitivity but low, resulting in many false positive results.
  • A relatively new test  can identify  patients who are at highest risk of anaphylaxis to peanut allergy versus  those who have just a sensitivity reaction.
  • ImmunoCAP is a  blood test  that identifies  the 5 proteins associated with peanut reactions.
  •  Ara h 1, Ara h 2, Ara h 3 and Ara h 9 are heat resistant proteins associated with potentially severe reactions, with Ara h 2 being the most important indicator of severe allergy.
  •  Ara h 8 is a heat liable protein that is most often found in people who have cross reactions to pollens and mild to no clinical peanut allergy symptoms.
  • Sublingual therapy has been linked to reducing the risk of anaphylaxis in severely allergic patients.
