The Security and Disaster Countermeasures Headquarters announced on the 25th that there may be various side effects to expand free diagnostic tests for all citizens of the new coronavirus infection (Corona 19) through rapid antigen tests. It was based on the arguments of some heads of local governments.
Tae-ho Yoon, head of Accident Control Headquarters, said in a regular briefing on the day: “(Standard test, nasopharyngeal swab) In the case of PCR, the test should not be pressed to report the results of test after 6 hours. ” It is, but if there are a lot of tests, it takes a long time to get the results. ”
If the inspection volume increases, the trial takes longer
He then mentioned the possibility of side effects. “In the case of foreign countries, cases have been reported that take more than a week to wait for the results of the PCR test,” said Yoon, head of quarantine, saying that “like the metropolitan area, the priority of evidence must be established. ”
For a rapid antigen test, the test result is obtained in 15 to 30 minutes. This is the reason why there is a view that “self-testing should be allowed”. However, the accuracy of the rapid antigen test is relatively low. Furthermore, if non-medical personnel self-examination is performed, the possibility of false negatives is higher.

Self-diagnosis of difficulty for rapid antigen testing
General Manager Yoon said, “There is a good chance that a false negative will appear on the rapid antigen test.” “This should also take into account the possibility of the overall test system shaking. “I will speak to Central Defense Response Headquarters about how to find potential (hidden) infected people in the community.”
The specimen collection method for the Rapid Antigen Test is the same as for the Nasopharyngeal Swab PCR. The cotton swab should be pushed deep at a flat angle toward the middle of the posterior part of the “inferior turbinate”, just above the roof of the mouth. Then an expert process is required to scrape off the secretion and absorb it into the tool. If the sample is not collected properly, there is a high possibility of a false negative.
