What are the diagnostic methods for infectious diseases?

The diagnosis is mainly based on medical records and photographic images (such as X-ray). However, the most important diagnostic tool for infectious diseases is microbial culture. The appropriate substances are provided in the culture medium and placed in the sample of the patient's sample. It is commonly used to diagnose staphylococcus or Bacterial infection of streptococcus. Some vectors cannot be cultured manually, especially most viruses and leptospirosis. In the past, the use of serological markers for the examination of patients has been developed, including the use of antibodies as one of the examination methods. Newer technology can directly use viruses or pathogen-related proteins in blood or secretions. As a polymerase chain reaction, not only the test speed is fast, but also the accuracy is greatly improved.


Identification of pathogens
In the past, according to the verification procedure of Koch's Law, it was possible to roughly confirm whether the pathogen of the disease is contagious. This rule successfully verified that Mycobacterium tuberculosis is the cause of tuberculosis; however, in many cases this rule cannot be operated as scheduled.

Confirm the popular range
The development of epidemiology is also very important for the study of diseases in ethnic groups. When an infectious disease breaks out, it is necessary to carefully separate the incidents into sporadic, endemic diseases, epidemics, pandemics, and the medical team and the public health department. Appropriate response measures.
