Abstract
Peanut allergen Ara h 6 is known to maintain IgE‐binding capacity upon exposure to digestive enzymes1 and its presence in circulation after consumption of peanut has been demonstrated.2,3 Therefore, it has been speculated that food‐derived allergens could be transferred via blood transfusion products, causing an allergic reaction in food-allergic recipients.4,5 However, in published case reports, presence of food allergen in donated material could not be confirmed due to lack of remaining transfusion material and/or lack of sensitive analytical methods. Using a newly developed sensitive immune‐assay for detecting Ara h 6 in human serum, we now report to what extent consumed peanut allergens can be present in blood transfusion materials and estimate the associated risk for peanut‐allergic recipients.
