Someone who is allergic to a particular compound (allergen) will often create a subtype of antibodies (immunoglobin E) to the allergen, and histamine levels will increase to produce the immune response. Although testing a particular food for the allergen is relatively straightforward, learning which potential allergen caused the response is much more challenging. Which might be the best technique to determine which allergen a person has been exposed to, and why

Answer:

To determine which allergen a person has been exposed to it is best to use Enzyme-Linked Immunosorbent Assay (ELISA) which is a plate-based assay technique designed for detecting and quantifying substances such as peptides, proteins, antibodies and hormones. This is because using an allergen in a sandwich ELISA will capture the antibodies produced against the allergen.
