Study Notes
Immunity
- Immunity is the body's ability to resist or eliminate harmful substances or abnormal cells.
- Foreign materials include viruses, toxins, carcinogens, fungi, and bacteria.
- Abnormal cells are cells that have changed from their normal form and function.
Serological Tests
- Serological reactions are in vitro antigen-antibody reactions used for disease diagnosis and identifying and quantifying antigens and antibodies.
- These techniques are "simple" because they directly demonstrate reactions without needing indicator systems or specialized equipment.
- Some examples of these tests include agglutination reactions and precipitation reactions.
Immunodiagnostic Methods
- Immunodiagnostic methods utilize antigen-antibody binding to identify and quantify specific antigens or antibodies in a sample.
- These techniques often involve electrophoresis, blotting, and labeled antibodies.
Types of Serologic Tests
- Primary binding tests directly measure antigen-antibody binding, like RIA and IF.
- Secondary binding tests measure the results of antigen-antibody interaction in vitro, examples include precipitation and complement fixation.
- In vivo tests measure the protective effect of antibodies in a host, such as passive cutaneous anaphylaxis.
Specimen Collection & Processing
- Serum and Plasma specimens must be free of gross contamination.
- Specimens should be received within 24 hours.
- Hemolyzed, lipemic, or bacterially contaminated specimens should be frozen unless specifically addressed.
