New detection method for new coronavirus approved by FDA

a novel coronavirus detection method using saliva samples was obtained by the US Food and Drug Administration for emergency use on 15 th. It has the characteristics of cheap, simple, fast and accurate, which is called “pioneering”. < / P > < p > the new coronavirus detection method, called saliva direct, was developed by Yale University researchers. It reduces the dependence on detection products and does not need to extract nucleic acid. < / P > < p > instead of swabs used for nasal and throat sampling, subjects only need to leave saliva samples in “any sterile container”. It does not use nucleic acid preservation solution or special test tube. The researchers said they found that the new coronavirus was “stable for a long time in a warm environment.”. In addition, the new method can use a variety of existing detection reagents and devices on the market. < p > < p > the FDA said that the new test method can reduce the demand for scarce testing resources and help improve detection capabilities. FDA director Stephen Hahn said it was a “groundbreaking” test “in terms of efficiency and preventing a critical shortage of testing supplies. < / P > < p > this is the fifth new coronavirus saliva test method authorized by the FDA for emergency use, and is funded by the U.S. men’s professional basketball league. Yale researchers have used this method to test American basketball players and staff. The comparison with the nasal swab test showed that the new saliva test was “highly sensitive” and the results of the two methods were “highly consistent”, more than 94%, the researchers said. < / P > < p > compared with pharyngeal swab and nasal swab test, subjects only need to leave saliva samples in the container, which reduces the risk of medical staff infected with virus, and there is no discomfort when swabs extend into nasal cavity and throat for sampling. The cost of other saliva tests approved by the drug administration is high, with market prices ranging from $75 to $150 per time, and results can only be produced within 48 hours, according to Yahoo News. < p > < p > Yale researchers say their goal is to develop fast and inexpensive assays that cost between $1.29 and $4.37. “We’ve simplified the test, so it costs only a few dollars on the reagent,” said Natan Gruber, one of the project’s leaders. “We expect the testing laboratory to charge only about $10 per sample.” < / P > < p > the researchers do not intend to profit from the new detection method, but will provide it to interested testing laboratories according to the open source agreement to help improve the detection ability. “Large scale testing is essential to control the epidemic,” Gruber said Scientists have made ultra-high-speed terahertz wireless chips that deliver faster than 5g
