Serology

Serology is a branch of clinical microbiology that studies blood serum to detect the presence of antibodies or antigens related to infections. When we're exposed to a pathogen, our immune system produces antibodies to fight it, and these remain in the bloodstream. By analyzing serum samples, healthcare professionals can identify past or current infections, determine immunity to certain diseases, or diagnose conditions. Serological tests are crucial for managing infectious diseases, guiding treatments, and understanding the spread of infections in communities.
