Molecular testing is highly sensitive and specific as compared to antigen or antibody based testing and has faster turn-around times than microbiological culturing. Molecular testing can help clinicians rapidly identify multiple infectious organisms which may be producing similar clinical symptoms. It can quantify the load of infectious agents much more effectively than conventional techniques and can monitor response to treatment accurately. And can simultaneously give information about antimicrobial resistance. These tests can diagnose micro-organisms with unusual clinical signs and symptoms, slow-growing/ uncultivable/ culture- negative infections.
