Nut allergy

NUT ALLERGY

There have been new guidelines published by the British Society for Allergy and Clinical Immunology (BSACI) for the diagnosis and management of peanut and tree nut allergy. BSACI suggests that component-specific IgE (Immunoglobiuin E) testing against specific proteins in specific nuts can offer a good prediction of who is at risk of a serious reaction, and how an individual may react to the nut in the future. BSACI recommends using a detailed history, skin-prick tests and a total nut IgE all together to diagnose an allergy. All patients should be prescribed antihistamines, with a personalised risk assessment of the need for adrenaline autoinjectors.
