HIV EIA (3rd generation immunoassay) - can use urine, saliva, or serum (most accurate), need to wait until 12 weeks post exposure to see antibodies, >99% accurate 4th generation immunoassay- "gold standard" measures P24 antigen can test 10 days post exposure Mast cell - Cellular bags of granules located in loose connective tisssue close to blood vessels. Activation initiates inflammatory process. Histamine - Causes vasodilation, increases vascular permeability, increases blood flow...

what is innate immunity -rapid response (hours) -fixed -limited number of specificities -constant during respone what is adaptive immunity -slow response (days to weeks) -variable -numerous highly selective specificities -improve during response examples of innate immunity -anatomical barriers: physical and chemical barriers -phagocytic cells: patrol bloodstream and tissue and rush to site of infection -complement: direct activities of some phagocytic cells what are the main adapti...
