The Central Disaster and Safety 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 testing. It was drawn on the arguments of some local government heads.
Tae-ho Yoon, head of the Central Accident Control Headquarters, said at a regular briefing on the day, “(Standard test, nasopharyngeal smear) In the case of PCR, the test must not be pushed to inform the test results after 6 hours.” It’s about, but if there are a lot of tests, it takes a lot of time to get the results.”
If the inspection volume increases, the judgment takes longer
– Next, he mentioned the possibility of side effects. “In the case of foreign countries, there are reports that it takes more than a week to wait for PCR test results,” said Yoon, head of quarantine, and said, “Like the metropolitan area, the priority of the tests should be set.”
In the case of a rapid antigen test, the test result comes out in 15 to 30 minutes. This is the reason for the opinion that “Self-test should be allowed”. However, the accuracy of the rapid antigen test is relatively poor. In addition, if the self-examination of a non-medical person is performed, the possibility of false negatives is greater.

Difficulty self-diagnosis for rapid antigen test
– General Manager Yoon said, “There is a lot of possibility that a fake negative will appear in the rapid antigen test.” “This should also take into account the possibility that the overall test system will be shaken. “I will discuss with the Central Defense Response Headquarters how to find potential (hidden) infected people in the community.”
The sample collection method for rapid antigen test is the same as for nasopharyngeal smear PCR. The cotton swab must be pushed deeply at a flat angle to the middle back of the’lower turbinate’, just above the roof of the mouth. It then requires a skilled process to scrape the secretions and absorb them into the tool. If the sample is not properly collected, there is a high possibility of a false negative.
