What is the study of antibodies and antigens in blood called?

The study of antibodies and antigens in blood is called [C] Serology. Serology is a branch of laboratory medicine that focuses on the detection and analysis of antibodies, antigens, and other immune markers present in bodily fluids, particularly blood serum. Serological tests are commonly used for diagnosing infectious diseases, autoimmune disorders, and assessing immune responses to pathogens or vaccines. These tests can detect specific antibodies produced by the immune system in response to infections or antigens, providing valuable information about the individual’s immune status and history of exposure to various pathogens.

Serology plays a crucial role in disease surveillance, outbreak investigations, blood typing for transfusions, forensic investigations, and monitoring the efficacy of vaccination campaigns. Overall, serology contributes significantly to the diagnosis, management, and prevention of infectious and immune-mediated diseases, enhancing public health efforts and patient care.
