Basically to explain this, an antigen is any type of pathogen that causes disease, while an antibody is something that combats against the antigen.
An antigen is a substance/molecule that, when introduced into the body, triggers the production of an antibody by the immune system, which will then kill or neutralize the antigen that is recognized as a foreign and potentially harmful invader.
Yes. An antigen is a substance that stimulates an animal in order to produce an antibody reaction to counteract the substance by a specific binding antibody-antigen. Most of the times this antigen is a molecule of protein.
Antibody is a sort of cells that are produced inside the body by immune system in response to the foreign particle/antigen.
An unexpected antibody in human blood means that a person does not have the antigen required to make a certain antibody because it is foreign to them. Unexpected antibodies are usually alloantibodies.
Antigens are substances that provoke an immune response (they're the ultimate target for the immune system). Antibodies are simply proteins that are secreted as a result of the antigen provoked immune response. In short, antigens cause the disease and antibodies cure it.
If it can be harmful, it can be referred to as pathogen.
