Since the COVID19 Pandemic has started, many COVID19 diagnostic tests have been put in use across the US and other parts of the world to contain the virus as soon as possible. However, a team of scientists has claimed that a new diagnostic test for COVID might be able to deliver the results much faster than any other existing diagnostic test. Experts have said that the new tool can accelerate the process of mass testing, which will help identify people, who need to stay in quarantine in a timely manner. It will help reduce the spread of the virus as well, said the experts. Scientists from the University of Birmingham in England have come up with this new diagnostic tool, which takes less than 5 minutes to find out whether someone has been infected with the SARS-CoV-2 virus. Contrary to previous COVID19 tests, the new test uses standard lab equipment and it does not require the usage of high heat on samples. Dr. Tim Daffron from the University of Birmingham School of Biosciences has said that new diagnostic test has an inherent sensitivity of an RNA test but it delivers the results much faster.
The new diagnostic test for COVID19 is known as the Exponential Amplification Reaction (EXPAR). It takes a single DNA strand as a sample to show the results, said the experts. Health officials have claimed that quick results of the diagnostic test can help control the pandemic much faster and speed up the process of mass testing. Dr. Andrew Beggs, who has been involved in the study, has said that more rapid testing will help unlock near-patient testing and getting people safely back to work. States have been struggling to provide enough testing and delivering the results to patients as soon as possible during the pandemic. The percentage of positive test rate is a key factor to understand how well a state is doing in terms of testing, said the experts.
Scientists from John Hopkins University have said that if the number of positive test results is too high or the total number of tests is low, the percent positive will be high. A high rate of the positive test shows a higher spread of the virus and it indicates that there are many people who have been infected with the virus and have not been tested yet. Health officials have set a target of keeping a positive test rate below five percent across the states. The data provided by John Hopkins University has shown that only two states have been able to meet the target, Vermont, and Hawaii. With the help of the new diagnostic tool, other states as well will be able to reach the target.
