Antigen

Health Care Term


Antigen is a substance that induces an immune response in the body and is specifically recognized by antibodies, T cells, or both. Antigens can be foreign, such as from microorganisms, or self-antigens, such as from cancer cells.

In healthcare, antigens play a critical role in the diagnosis and treatment of diseases. For example, when a pathogen enters the body, it carries antigens that trigger an immune response to fight off the infection. In diagnostic tests, such as the COVID-19 antigen test, samples are tested for the presence of specific antigens to determine if an individual is infected with the virus.

In addition, antibodies produced by the immune system in response to antigens can be used in diagnostic tests such as the antibody test for COVID-19. This test detects the presence of antibodies in a blood sample of a person, indicating that they have been infected with the virus in the past.

Antigens also play a vital role in vaccines. Vaccines introduce harmless antigens into the body, which stimulate an immune response, leading to the production of antibodies. In this way, vaccines help protect individuals from infections by priming their immune system to recognize and fight off future infections.

In summary, antigens are a critical component of the immune response and play an essential role in the diagnosis, treatment, and prevention of diseases, making them a crucial tool in the healthcare industry.
