Immunological examination

Immunological test is a physiological function test that the body recognizes the "self" and "non-self" antigens, forms natural immune tolerance to autoantibodies, and has a rejection effect on the "non-self" antigens. Under normal circumstances, this physiological function is beneficial to the body, and can produce anti-infection, anti-tumor, etc. to maintain the body's physiological balance and stable immune protection. Under certain conditions, when the immune function is dysfunctional, it can also produce harmful reactions and results to the body, such as triggering hypersensitivity reactions, autoimmune diseases, and tumors.
