An antigen is a substance that can trigger an immune response in the body. It is usually a foreign substance, such as a virus or bacteria, that the immune system recognizes as a threat and produces antibodies to fight off. Antigens can also be found on the surface of cells in the body, helping the immune system to distinguish between self and non-self. **

An antigen test for patients is a diagnostic test that detects the presence of specific proteins, known as antigens, on the surface of a virus or bacteria. This type of test is commonly used to quickly identify the presence of an active infection, such as COVID-19. Antigen tests are often performed using a nasal or throat swab and provide rapid results, usually within 15-30 minutes. These tests are less sensitive than PCR tests but are valuable for quickly identifying individuals who are currently infected and may be contagious. **
