IgE is an allergy-related antibody, Chang explains, and people in different environments produce different types of IgE. When the surface ligands of mast cells and basophil cells in sufferers 'immune systems are all occupied by IgE, it forms a kind of army waiting to take action (which can last for months to years).
而 IgE 正是一種與過敏有關的抗體，張子文解釋，人在不同的環境中會產生不同的 IgE，當患者免疫系統中的巨大細胞與嗜鹼細胞的表面「結合子」都被 IgE 佔據時，便形成一種「武裝部隊已蓄勢待發」的敏感體質（可以歷時數月到數年之久）。
