As Corona 19 in Korea is rapidly spreading across the metropolitan area, a large-scale preventive diagnostic test will begin today (14) at a temporary screening clinic in the metropolitan area.
According to the Central Defense Countermeasures Headquarters (Bang Dae-bon), the government establishes an ‘intensive inspection period’ of three weeks from today until the 3rd of the following month, and conducts free inspections at 150 temporary detection clinics in the metropolitan area.
Since the goal is to find “ asymptomatic patients ” early by lowering the barrier of the corona test, 19 temporary screening clinics are located in areas with good access and “ anonymous tests ” that do not collect are possible. other information other than mobile phone numbers.
Also, according to Bang Dae-bon’s new ‘Crown Response Guidelines 19’, you can get tests for free even if you have no suspicious symptoms or epidemiological associations with confirmed cases.
The specific locations of 150 temporary clinics will be revealed today via a briefing by the Security and Disaster Countermeasures Headquarters.
In Seoul, it is known to include the main university districts, Seoul Station, Yongsan Station, and Tapgol Park in Jongno-gu.
In the case of Goyang City, three transportation hubs, including Hwajeong Station, Jeongbalsan Station, and Ilsan Station Exit on the Gyeongui Line, were added as temporary detection stations.
Temporary clinics are open from 9 am to 6 pm on weekdays and on weekends.
810 people are also employed to support epidemiological investigations, including military, police and apprentices.
In addition to the existing ‘PCR test’ (Nasopharyngeal smear gene amplification test method), two new test methods, such as the ‘Live Animal PCR Test’ and the ‘Rapid Antigen Test’, have been introduced to increase the convenience of testing.
Citizens undergoing COVID-19 testing can choose any of the three test methods, but quarantine authorities recommend that they be performed in the order of Nasopharyngeal swab PCR → Saliva PCR → Rapid antigen in consideration of the precision.
In particular, if you have any symptoms or if the confirmed person and the flow line overlap, it is recommended to undergo a nasopharyngeal swab PCR test.
The standard test method used in diagnostic tests in Korea is the nasopharyngeal smear PCR test with the highest precision.
If two or more characteristic Corona 19 genes are positive in a sample collected with a cotton swab from the inside of the nose, it is considered confirmation.
It is the most accurate among the three test methods and is also used as a worldwide standard test method.
The test results take approximately 24 hours to appear.
The saliva sample PCR is the same as the conventional PCR test, but a sample is obtained with a needle instead of placing a cotton swab in the nose.
Since the patient spits saliva directly into a separate specimen collection container, specimen collection is easy and the risk of infection due to the spread of saliva droplets is low.
In the temporary screening clinic, the nasopharyngeal smear PCR test is basically used, but the applicant can perform the saliva PCR test instead.
However, the sensitivity is slightly less than when using a nasopharyngeal sample, up to a level of 92%, so it is recommended to perform it in a lower order than the general PCR test.
Rapid antigen testing is a test method that checks for the presence of components of the corona 19 virus by collecting a sample from inside the nose.
If the PCR test method previously tested the virus itself, the rapid antigen test is to detect antibodies generated by the body’s immune response when the Corona 19 virus enters the body.
If an antigen is detected in a sample, it can be assumed to be positive, that is, an infected state.
The advantage is that you can verify the results immediately after waiting 30 minutes to 2 hours on the site after the inspection.
However, since the precision is somewhat lower than that of the PCR test, if the rapid antigen test result is positive, you must perform an additional PCR test to check for infection.
