Molecular and antigen tests detect whether a person is currently infected, and serology detects whether a person had an infection in the past. This minimizes non-specific binding that leads to false positives and high background noise. An antibody has a lock-like structure at each tip of its “Y” which fits a specific key-like structure located on an antigen. 2. Antigens are "targeted" by antibodies. Antibodies are made up of four polypeptide chains, which are arranged in a Y-shape. Difference between Antigen COVID Rapid Tests vs. Antibody COVID Rapid Tests.
