Immunology and Cell Biology

Diagnostic Immunology. Immunoassays are laboratory techniques based on the detection of antibody production in response to foreign antigens. Antibodies, part of the humoral immune response, are involved in pathogen detection and neutralization.

Diagnostic immunology has considerably advanced due to the development of automated methods.New technology takes into account saving samples, reagents, and reducing cost.The future of diagnostic immunology faces challenges in the vaccination field for protection against HIV and as anti-cancer therapy. Modern immunology relies heavily on the use of antibodies as highly specific laboratory reagents. The diagnosis of infectious diseases, the successful outcome of transfusions and transplantations, and the availability of biochemical and hematologic assays with extraordinary specificity and sensitivity capabilities all attest to the value of antibody detection.Immunologic methods are used in the treatment and prevention of infectious diseases and in the large number of immune-mediated diseases. Advances in diagnostic immunology are largely driven by instrumentation, automation, and the implementation of less complex and more standardized procedures.

Examples of such processes are as follows:

• miniaturization (use of microtiter plates to save samples and reagents),
• amplified  immunoassays (chemiluminesent ELISA),
• flow cytometry with monoclonal antibodies,
• Immunoglobulins,
• Molecular methods (polymerase chain reactions).

These methods have facilitated the performance of tests and have greatly expanded the information that can be developed by a clinical laboratory. The tests are now used for clinical diagnosis and the monitoring of therapies and patient responses. Immunology is a relatively young science and there is still so much to discover. Immunologists work in many different disease areas today that include allergy, autoimmunity, immunodeficiency, transplantation, and cancer.
