Document Summary
Lecture 25: high risk behavior and the aids test . Negative for hiv-1 and hiv-2 antibodies and p24 ag. *know what happens as far as testing is concerned. ***4th generation tests look for both antigen and antibody, thus detecting hiv earlier than previous testing would. Specificity > 99. 9% (when combined with elisa) Proteins are located on the outer layer of the virus. There are also inner proteins (including p34--the core protein surrounding the nucleic acid). Antibodies are the response to invading viruses. Well is coated with hiv antigen patient"s serum is added anti-human antibody with attached enzyme is added substrate to enzyme is added. The elisa test: a color change in the final step indicates that the patient has hiv antibodies in their bloodstream. Principles of the 4th generation hiv antigen-antibody assay*** The 4th generation hiv-antigen-antibody assays contain components that will detect. Hiv-1 p24 antigen, antibodies to hiv-1 p24 antigen, antibodies to hiv-1, and antibodies to hiv-2.
