Serological test , any of several laboratory procedures carried out on a sample of blood serum, aimed specifically at the detection of antibodies or antibody-like substances that appear in association with certain diseases. Serological tests are particularly helpful in the diagnosis of infectious diseases. Learn what serological tests are, how they work, and why they are used to detect and diagnose infections. Find out the different types of serological tests, such as ELISA, Western blot, and rapid diagnostic tests, and their advantages and limitations. A serological test is a diagnostic method that examines blood serum to detect the presence of specific antibodies or antigens. The core principle relies on the highly specific binding that occurs in an antigen-antibody reaction. These tests are crucial for identifying infections, autoimmune diseases, and checking for immunity against certain diseases. Serological tests are used to diagnose Brucellosis, HIV, Measles, Rubella, Amebiasis, Syphilis and several fungal infections. Serological blood tests employ various advanced techniques to focus on immune system-produced proteins. Serology , in the broader context, studies serum and bodily fluids, identifying diagnostic significance of antibodies.
