Microbiology provides services for the diagnosis of infectious diseases of a bacterial, viral, parasitic, fungal or tubercular nature. In addition to routine diagnostic methods (cultural and microscopy), automated systems aid in the rapid detection of infectious agents in blood or body fluids. Automated systems for identification of microorganisms and their susceptibility to antimicrobials further expedite reporting which may be life-saving for patients..

Special microscopy (fluorescent and dark-field) helps in rapid diagnosis of tuberculosis and viral infections. Serological investigations are also performed for a variety of infectious agents (including viral agents such as HIV and Hepatitis viruses).
