Mr. Nguyen Tu Quang: ‘Bkav uses salt water to rinse his mouth to test for Covid-19’

According to CEO Nguyen Tu Quang, testers only need to gargle with salt water, then take this solution to be tested to be able to identify the virus infection.
This is the statement made by Mr. Nguyen Tu Quang at the event “How AI, Blockchain contribute to the fight against the epidemic”. Accordingly, the head of Bkav affirmed that the company is developing technology to help find people infected with Covid-19 through physiological saline solution.

Explaining the mechanism of action of this method, Mr. Quang said, test participants will be gargling with salt water. This solution is then put into a test tube and placed in the test device. If in other methods, the time to return the results will take from half an hour to several hours. Meanwhile, with this method, it only takes 10 seconds to produce results, Mr. Quang shared.

Bkav’s artificial intelligence technology will help measure how much frequency is absorbed. Different frequencies of absorption produce different types of disease, in this case Covid-19. Mr. Quang said: “The naked eye can’t recognize the difference of those absorption frequencies. We have to train the AI ​​to know which is the specimen of the Covid patient and which is the human sample. not infected with Covid-19”. According to Quang, Bkav’s method of testing for Covid-19 with saline mouthwash solution will give faster results than conventional methods. The founder of Bkav company said that compared to the method of testing Covid-19 by breath, the salt water test technology is simpler, with the investment money for a testing unit much cheaper, even almost no cost. This test method has been tested by Bkav since the end of 2020 at the Central Hospital for Tropical Diseases. “Initial results were recorded as positive with a recognition rate of over 90%,” Mr. Quang said. According to CEO of Bkav, this business is the second company in the world to develop saline testing technology. Previously, a company in Israel had developed this technology.
