The new crown epidemic continues, and a new round of outbreaks has made Tuen Mun a hardest-hit area, and many citizens are required to undergo mandatory testing.
Earlier, there were long queues at various testing stations in the district.
The Home Affairs Department purchased 300,000 rapid test kits for the novel coronavirus this month, which are expected to be distributed in 18 districts so that beneficiaries can conduct rapid tests on their own.
Zhao Yantao, an adjunct associate professor at the School of Biomedical Sciences of the Chinese University of Hong Kong and developer of the INDICAID® Duoyi® New Coronavirus Rapid Antigen Detection Reagent, hopes that this move will help the authorities to find invisible patients in the community as soon as possible and cut off the chain of transmission, and it will also make people worried Make a quick test yourself, and enjoy the New Year with peace of mind.
At present, testing is mainly divided into compulsory testing and "exhaustive testing". However, nucleic acid testing in Hong Kong can only process about 100,000 samples per day. Once more than 100,000 people are tested, it will cause some citizens to delay receiving the results.
Zhao Yantao, an adjunct associate professor at the School of Biomedical Sciences of the Chinese University of Hong Kong and developer of the INDICAID® Tuoyi® novel coronavirus rapid antigen detection reagent, pointed out that the variant virus Omicron is characterized by high transmission and short onset time, and changes rapidly in the human body. There may be loopholes in the policy of "one test every three days". For example, an invisible patient may be tested negative three days ago, but may suddenly become positive three days later.
He believes that if a rapid test is added during the "three-day inspection" period, it will be more helpful to find patients quickly and isolate patients before the transmission chain is formed. Therefore, he decided to provide the government with 300,000 quick tests at a cost close to the cost. Test kits and distribute them in the community.
How to use the quick test kit
Rapid test kits are 86.4% accurate
Rapid test kits have passed the latest clinical tests in Florida, USA.
When patients arrive at the clinic for consultation, they will provide rapid test kits to test themselves, and after the results are obtained, they will be compared with the nucleic acid test.
It was found that its accuracy was as high as 86.4%.
Zhao Yantao mentioned that they are not only product developers, but also government-approved nucleic acid testing institutions. Citizens can use rapid test kits by themselves. If there is a positive result, they can call the hotline first. Nucleic acid tests, if the results are indeed true positives, will be reported to the Department of Health in real time, reducing the burden on the government.
Zhao Yantao said that although the rapid test kit is cheaper and faster than the nucleic acid test, it is not intended to replace the nucleic acid test, emphasizing that the rapid test kit is only an auxiliary tool.

He mentioned that in 2020, Sanatorium and Hospital introduced the INDICAID® Tuoya® New Coronavirus Rapid Antigen Detection Reagent to conduct rapid tests for admitted patients, and then arrange hospitalization after negative results.
To ensure accuracy, they will conduct a two-track test, that is, the remaining solution from the rapid test will be sent to a central laboratory for nucleic acid testing.
In November of the same year, a confirmed case of the "dancing group" appeared in Sanatorium and Hospital. Due to the lack of time, all medical staff immediately conducted a rapid test and successfully found an invisible patient in a short period of time.
If only the nucleic acid test was used for testing at that time, it would take a long time, or the confirmed patients could not be isolated in time.
He pointed out that the purpose of the current distribution plan is to allow those who are concerned to test themselves and avoid spreading the virus to others. In particular, the fifth wave of the epidemic broke out before the New Year, and New Year's greetings are a Chinese tradition. It is inevitable that some people will need to attend small family gatherings. Want to suppress the spread before the new year.
He suggested that the public should take an extra step before attending any activities with a risk of infection, conduct a rapid test on their own, and have more peace of mind, but at the same time, they should reduce unnecessary gatherings to avoid increasing the risk of transmission.
