“Only one line came out. Voice.”
At 10 am on the 15th, SD Biosensor headquarters in Suwon, Gyeonggi-do. This is the result 15 minutes after receiving a rapid antigen test for novel coronavirus (Corona 19) infection with a rapid antigen diagnostic kit. According to the Ministry of Food and Drug Safety, SD Biosensor’s product is the only rapid antigen diagnostic kit that has been officially approved in Korea.

Rapid antigen testing is a method of testing for antibodies generated by the body’s immune response when the Corona 19 virus enters the body. The advantage is that you can get results in 15 minutes and that you can perform the test anytime, anywhere with a diagnostic tool. The diagnostic tool, reminiscent of a pregnancy test, is as light as 4g.
The inspection method is simple. Place a sterile cotton swab in the nose to collect the sample, place it in the Extraction Solution tube containing the reagent and swirl at least 5 times. Then clamp the tube firmly and drop three drops into the scan tool. You can immediately see that the sample mix is spilling into the results window in the diagnostic tool. The result is displayed in 30 minutes. If a line appears only on line C in the output window, it is negative, and if lines C and T are visible, it is positive. Simply put, if two lines appear, it means it is considered positive. At this time, it is interpreted as a significant result even if the lines are barely visible. More accurate results can be obtained by using it at the beginning of infection with a large number of viruses in the body.
Lee Jun-hwang, head of the second and fourth team of the SD biosensor sensor development team, said: “The biggest advantage is that you can immediately test every person who wants to test without additional costs. I think it’s good to take care of it and keep getting tests done. ”
“An avalanche of inquiries”

The quarantine authorities introduced a new rapid antigen test in the temporary screening clinic in the metropolitan area, which has been operating since the 14th. The cost is free. In general hospitals, rapid antigen tests can also be done. In emergency rooms, intensive care units and medically vulnerable areas, 50% of the health insurance applies, so the copay is about 8,000 won. General medical institutions that are not covered by insurance may also be tested for default. Due to the convenience of testing, front-line hospitals and screening clinics are receiving inquiries about rapid antigen tests. An official at an otolaryngologist in Seoul, who promoted that the rapid antigen test was available for 35,000 won, said: “Because the test is convenient, many people want to receive a rapid antigen test or ask questions related to the test.” .
Quarantine authorities are in the position that rapid antigen testing is an adjunct to the existing “PCR test method (nasopharyngeal smear gene amplification test method)”. Citizens currently undergoing COVID-19 testing at temporary screening clinics can choose from Nasopharyngeal (runny nose) smear PCR, saliva PCR, and rapid antigen test. Considering the precision of the test, quarantine authorities recommend that the test be performed in the order of nasopharyngeal swabs PCR → saliva PCR → rapid antigen.
In particular, if you have any suspicious symptoms, or if the confirmed person and the flow line overlap, it is better to have a nasopharyngeal swab PCR method. If the rapid antigen test result is positive, you must perform an additional PCR test to check for infection. Self isolation is required until results are obtained. A quarantine authorities official said: “When the precision of the nasopharyngeal swab PCR test is 100, the precision of the saliva PCR test and the rapid antigen test is a little lower than that.” It is an auxiliary means of proof. ”
