Condition/domain being studied
The main domain being investigated is IgE-mediated food allergy. We will explore any food allergen. Food allergens will be ranked by the frequency of available studies and index test, with the most commonly investigated allergen prioritised, if necessary. This is because we will assume that more studies will raise more high-quality studies, thus firming evidence. Next, the more recently developed tests (CRD, BAT, MAT) will be prioritised according to the frequency of reports. The previous EAACI Food Allergy Guideline paper has already given recommendations for SPT and specific IgE, and we aim to summarise novel evidence on SPT and specific IgE if this seems warranted.
