About Us

The Serological Analysis Group is responsible for testing patient's blood or serum for the presence of antibodies to or antigens from various disease organisms.

Antibodies are proteins that are produced by a human or animal host in response to a foreign substance known as an antigens. An antigen is usually a protein or carbohydrate, and it is part of an infectious agent such as a virus or bacterium. The antibody attaches to the antigen and aids the host in removing the infectious agent. Serology is the branch of medical science that deals with detecting the presence of a disease by detecting antibodies or antigens.
