How do blood types get determined? Blood bank specialists determine blood types based on whether there are particular antigens on your red blood cells. An antigen is a substance that can make your body’s immune system react. Think of an antigen as a marker (like a nametag) that identifies a substance in your body as belonging or not belonging.
