With the joint efforts of people from all walks of life across the country, the epidemic in our country has been fully and effectively controlled. With the beginning of resumption of work and production, nucleic acid testing for the new coronavirus has become an effective means of population screening and health certificates. How much do you know about nucleic acid testing for the new coronavirus?
Nucleic Acid Test for the New Coronavirus
Confirmation of COVID-19 depends on the detection of infected pathogens, especially the detection of infected pathogens based on molecular biology , including real-time fluorescence RT-PCR and gene sequencing. However, due to the high requirements, long time and high cost of gene sequencing equipment, it is not suitable for routine clinical testing. The current method for nucleic acid testing of the new coronavirus is real-time fluorescent RT-PCR. The detectable specimens include nasopharyngeal swabs, sputum, alveolar lavage fluid, feces and anal swabs, etc. Given the convenience of sampling and the accuracy of diagnosis, the current detection specimens screened by the population are nasopharyngeal swabs. For patients who are strongly suspected of being infected with the novel coronavirus but initially tested negative, resampling should be repeated from multiple sites of the respiratory tract. Other types of samples (such as blood, urine, feces) can also be collected to detect virus conditions in different parts.
Novel Coronavirus Antibody Test
The latest version of the diagnosis and treatment plan, serum novel coronavirus-specific IgM and IgG antibodies were positive; IgG antibodies changed from negative to positive or had a 4-fold increase in the recovery period compared with the acute phase, which can also be used as diagnostic criteria. IgM is an early antibody produced after an infection of the body, indicating a dysfunctional infection; while IgG indicates a previous infection. The novel coronavirus antibodies can be used as a supplement to nucleic acid detection in , reducing the problem of false negative nucleic acid detection. However, antibody testing cannot replace nucleic acid testing and cannot be used for screening of the general population.
At present, nucleic acid testing for the new coronavirus is still an important and effective means for screening for ordinary people who resume work and production. If there is such a need, you can go to the screening clinic of Beijing You'an Hospital affiliated to Capital Medical University for testing.
1.Voluntary self-funded testing.
2. Testing process: 8:00 am to 15:00 am on weekdays (Monday to Friday), please go to the screening clinic on the north side of Building A of Beijing You'an Hospital to register and issue the inspection form "Two reagents for new coronavirus ribose nucleic acid test (self-screening)". After paying the fee, leave a pharyngeal swab specimen.
3. Test results are issued within 48 hours after screening.
4. Consultation phone number 010-63292123. Group screening of more than five people requires reservation in advance.
