At present, immunological detection methods are mainly applied to blood specific Ig M, Ig G antibodies and new coronavirus antigens. Compared with molecular biological detection, it takes less time, is simple to operate, and has different sensitivity at different stages of the disease. More suitable for epidemiological screening.
Recently, there are also reports in the literature that new novel coronaviruses have been detected in the feces of infected patients. It sounds like a new detection method, in fact, it is also based on the detection of viral nucleic acid in stool samples. In addition, some researchers have cultivated coronavirus in stool samples, and then conducted virus identification based on molecular biology methods. Although the cultivation method is the gold standard for pathogenic testing, due to the long cultivation period and high laboratory requirements, it cannot be fully developed at present.
The different detection methods of new coronaviruses have different principles. Whether it is immunological detection or molecular biological detection, each test method has its limitations. Therefore, experts from the Chinese Center for Disease Control and Prevention recommend that different methods be used in the diagnosis of new coronaviruses. Different types of kits, make up for the shortcomings. At the same time, the results of CT imaging cannot be ignored, and comprehensive diagnosis and treatment should be combined with the clinical symptoms of patients.
