(KGTV)- UC San Diego Health has had a goal to increase testing since the start of this pandemic, according to Dr. David Pride, the Associate Director of Microbiology.Now, UCSD Health has started using a new testing strategy; pool testing.“We’ve really been thinking about what is it that we can do to sort of extend testing in the San Diego region,” said Pride. “Pooling is absolutely a strategy, for example, that employers can use on their employees that universities can use, for example, on their students.”As the nation faces another COVID-19 testing supply shortage, Pride said this could be one solution to conserving the current supply.“Pool testing works by taking a group of individuals and placing all of their specimens together,” he said.Instead of using one test per person, samples from several people are collected and tested together.The Centers for Disease Control and Prevention recommends pool testing to be used only when the positive rate is low enough to justify pooling.“If that pool tests negative, then you can call each individual that was in that pool negative,” said Pride.If the pool tests positive, then each person is retested individually.“We test a lot of different patient populations, so we know what the prevalence of disease is in those patient populations, and we’ve chosen to use those with the lowest prevalence of disease for our pool testing,” Pride explained.He said they are currently using a five to one strategy, meaning five people per one test.“We’ve done probably somewhere around 500 to 600 so far. The majority of the batches have been negative, we’ve had less than 10 percent of the pools test positive,” Pride said, which is what his team expected.Pride said he heard positive feedback about pool testing from the Food and Drug Administration (FDA).“Just a few weeks ago, we submitted our emergency use authorization to the FDA, and we think we’re probably getting fairly close to that getting approved,” he said.Soon, pride expects to start doing more pool testing, while also speeding up the process.“Right now, we’re really working on it in a very manual fashion,” he said. “That takes a lot of time to do, so we’re in the process of automating it by bringing in machinery to do that work that people are doing right now.” 2287

A 9-year-old boy retrieved a gun from his parents' bedroom and shot his 13-year-old sister to death, authorities said, after the two got into an argument over a video game controller.The incident occurred over the weekend in rural Monroe County, Mississippi, as the children's mother was preparing lunch in the kitchen, the country sheriff said."He wanted the controller, and I guess he knew where to find the gun," Sheriff Cecil Cantrell told CNN.The boy grabbed a handgun, which was kept in a nightstand next to the bed, and shot the sister in the back of the head, the sheriff said."This is the first time I've ever dealt with any child that was shot like that," Cantrell said. "And I hope I never deal with it again."The girl was taken to Le Bonheur Children's Hospital in Memphis, where she was pronounced dead Sunday.The case is still under investigation and authorities have not filed charges."We are talking to the district attorney," Cantrell said.The-CNN-Wire 977
