snoop1130 Posted May 6, 2020 Share Posted May 6, 2020 Yala lab cleared of major malfunction after reporting 40 false positives Medical authorities have sought to allay public fears about the accuracy of Covid-19 testing after 40 results delivered by a Yala laboratory last week were found to be false positives. Dr Opas Karnkawinpong, director-general of the Department of Medical Sciences under the Health Ministry, explained that the control samples of pure water used at the Yala lab had tested positive rather than negative, indicating a problem had occurred in the process. As soon as the problem was discovered, all testing was stopped at the lab and the 40 samples were sent for retesting at the Songkhla Department of Medical Sciences. All 40 retested samples came back negative for Covid-19. The samples were then sent for a third round of testing at the Department of Medical Sciences in Bangkok, which confirmed the results were negative. Opas added that laboratory testing was only one method of detecting Covid-19 cases, which could also be traced by investigating people’s travel histories and reports of infections in each community. A team investigating the false-positives at the lab in Yala found no major structural errors but said the testing process could be improved to ensure better performance. However, Opas noted that Yala was the first province in deep South to create a lab for Covid-19 detection, meaning it had a high workload of more than 4,000 samples tested so far. As such, the department would support the facility with an equipment upgrade and ask nearby labs to help carry the burden of testing. These moves would help control the spread of the virus, he said. The Yala lab would reopen in a few days after being upgraded, and rejoin the battle against the contagion, Opas added. “Errors can occur during testing. The most important thing is that they found the root problem, which will help reduce flaws in our mission to detect Covid-19 cases,” he said.

DrTuner Posted May 6, 2020 Share Posted May 6, 2020 (edited) Uh-huh, control samples of pure water you say... Now explain to me how would a fluorescent probe reagent indicate positive in any other case other than actually having reacted to the presence of SARS-CoV-2.

DrTuner Posted May 6, 2020 Share Posted May 6, 2020 Quote Opas noted that Yala was the first province in deep South to create a lab for Covid-19 detection, meaning it had a high workload of more than 4,000 samples tested so far. How many days did that 4000 take, any guesses? So one lab in "deep south", whatever that area may be, with that testing capability. Link to comment Share on other sites More sharing options...

webfact Posted May 6, 2020 Share Posted May 6, 2020 Machine error blamed for 40 false positive tests for COVID-19 in Yala Machine error has been blamed for the 40 recent false positive test results for COVID-19 in Thailand’s southern province of Yala. Dr. Opas Karnkavinpong, director-general of the Medical Science Department, told a news conference this afternoon (Wednesday) that health officials conducting COVID-19 lab tests found something unusual about the standard control protocol of the RT-PCR tests, done under the Active Case Finding (ACF) campaign. He explained that, in the RT-PCR lab test protocol, there are two standard controls, one positive and one negative, adding that the results of the positive and negative controls must always be positive and negative respectively and, if the results deviate from this, the officials must immediately suspend the tests.
