Microbiological testing plays a very important role in diagnosing infections to find the cause of the disease, thereby helping doctors have the most effective treatment plan. Microbiological testing includes many testing methods and depending on the type of infection, the doctor will order different microbiological tests.

Molecular biological testing is of confirmatory significance in the diagnosis of infectious diseases. However, this method cannot perform antibiotic susceptibility testing. To evaluate the results of immunological tests, it is necessary to rely on the pathogenesis of each type of microorganism.

Respiratory infections are caused by a multitude of pathogens, mainly bacteria and viruses. However, clinical symptoms specific to the pathogens are often few, leading to misdiagnosis and overtreatment with antibiotics. Therefore, correct diagnosis of the infectious agent for appropriate antibiotic treatment is very important.
