Abstract
Purpose of review: As an ex-vivo test of allergic effector cell activation, basophil activation testing (BAT) to allergen enables quantification of the in-vivo IgE-mediated allergic response. BAT thus holds promise in the diagnosis and monitoring of peanut and tree nut allergies. Recent systematic analyses and expert recommendations support a role for BAT in the diagnosis of peanut and tree nut allergy.
Recent findings: Diagnostic cut-offs for BAT in peanut and tree nut allergy have been identified. Consistently, BAT can discriminate with high sensitivity and specificity between allergy and tolerance when measured against oral food challenges. Furthermore, the utilization of BAT has can increase the sensitivity and specificity of peanut allergy and tree nut allergy diagnosis, both alone and in conjunction with specific IgE testing and skin prick testing. BAT is a promising tool in the diagnosis of peanut and tree nut allergy.
期刊介绍：
The aim of Current Allergy and Asthma Reports is to systematically provide the views of highly selected experts on current advances in the fields of allergy and asthma and highlight the most important papers recently published. All reviews are intended to facilitate the understanding of new advances in science for better diagnosis, treatment, and prevention of allergy and asthma.
We accomplish this aim by appointing international experts in major subject areas across the discipline to review select topics emphasizing recent developments and highlighting important new papers and emerging concepts. We also provide commentaries from well-known figures in the field, and an Editorial Board of internationally diverse members suggests topics of special interest to their country/region and ensures that topics are current and include emerging research. Over a one- to two-year period, readers are updated on all the major advances in allergy and asthma.
