Tips on allergen testing

What is commonly called allergen testing does not actually detect allergen molecules in blood samples, but indirectly detects the specificity for a certain allergen. IgE molecules.

Introduction to IgE molecules

Human immune cells are currently divided into three types, namely TH1, TH2 and Treg. In a healthy state, TH1 and TH2 balance each other and are jointly regulated by Treg. When Treg regulatory capabilities are insufficient or exposed to certain proteins or small molecules (foods such as dust mites, pollen or seafood), TH2 will be overactivated, resulting in excessive secretion of TH2 cytokines, which will help B cells to produce more Allergic antibody IgE, resulting in allergic symptoms.
