Coronavirus is a type of RNA virus that exists widely in nature. Infection with this virus will manifest as different clinical symptoms from the common cold to severe pneumonia. The coronavirus first discovered in Wuhan in December 2019 is a strain of virus that has not been previously found in humans. The WHO officially named it"2019 Novel Coronavirus (2019-nCov)". The use of nucleic acid diagnostic kit can quickly and accurately detect viruses and provide reference for disease prevention and control and clinical diagnosis and treatment.
Novel Coronavirus Pneumonia According to the "New Coronavirus Infection Pneumonia Diagnosis and Treatment Plan (Trial Fifth Edition)", two methods are mainly used for nucleic acid detection, one is real-time fluorescent RT-PCR kit detection, and the other is virus gene sequencing . Nucleic acid detection kits can obtain test results faster, and are more suitable for the current epidemic prevention and control, and management, so most of them use nucleic acid detection kits for diagnosis.
Use the corresponding nucleic acid detection kit to detect the nucleic acid of the novel coronavirus in respiratory specimens or blood specimens, and prove the presence of the novel coronavirus in the patient's respiratory specimens or blood specimens, which is an important basis for the diagnosis of novel coronavirus pneumonia.
Due to sample collection, storage, transportation, and technical reasons, the current nucleic acid detection kit for novel coronavirus infection has a certain false negative problem (that is, the testee has a novel coronavirus infection, but the nucleic acid test result is negative).
At present, comprehensive judgments are also made through repeated nucleic acid detection and imaging examination results to reduce the possibility of undetected infections.
