New coronavirus nucleic acid testing is the "gold standard" for confirmed cases. The early symptoms of new coronary pneumonia are very similar to the flu. How do doctors make judgments quickly and accurately? Laboratory test results are key. In the fight against the current epidemic, choosing appropriate scientific rapid detection methods can quickly diagnose patients, isolate them quickly, and take measures quickly.

On March 4, the General Office of the National Health and Health Commission officially issued the "New Coronary Virus Pneumonia Diagnosis and Treatment Plan (Trial Version 7)" to local health and health commissions.

1. Newly added serum novel coronavirus-specific IgM/IgG antibody detection as one of the diagnostic criteria

2. The exclusion criteria for suspected cases have been improved: in addition to continuing to use two consecutive negative nucleic acid tests (with an interval of 24 hours), the new coronavirus IgM/IgG antibody test is negative 7 days after the new onset, and the diagnosis of suspected cases can be excluded.

Detect whether the subject carries the RNA fragment of the new coronavirus to determine whether it is infected by the virus. The application of real-time fluorescence quantitative PCR detection technology to achieve accurate detection of new coronavirus RNA is currently the "gold standard" detection technology for rapid virus identification recommended by the World Health Organization.

IgM antibodies are the first antibodies secreted in the immune response and the earliest antibodies in the autoimmune process of virus infection, which can be used as a marker of recent acute infection. IgG appears later than IgM and can exist for a longer period of time, and elevated IgG usually indicates previous or chronic infection.

Tenren Medical Laboratory strictly follows the requirements of the "Technical Guidelines for Laboratory Testing of Novel Coronavirus Pneumonia" (Fifth Edition), and does a good job in specimen collection and processing, packaging, storage, transportation and inspection, and laboratory testing. Provide professional on-site sample collection services, and can provide appointments for door-to-door sampling services, layer by layer control, to ensure the health and safety of personnel. The laboratory will issue a report within 12 hours after receiving the sample. For samples sent to the laboratory before 16:00 pm every day, the report will be issued before 24:00 that evening.
