Potential accuracy issues with a widely used coronavirus test could lead to false results for patients, U.S. health officials warned.The Food and Drug Administration issued the alert Monday to doctors and laboratory technicians using Thermo Fisher’s TaqPath genetic test. Regulators said issues related to laboratory equipment and software used to run the test could lead to inaccuracies. The agency advised technicians to follow updated instructions and software developed by the company to ensure accurate results.The warning comes nearly a month after Connecticut public health officials first reported that at least 90 people had received false positive results for the coronavirus. Most of those receiving the false results were residents of nursing homes or assisted living facilities.A spokeswoman for Thermo Fisher said the company was working with FDA “to make sure that laboratory personnel understand the need for strict adherence to the instructions for use.” She added that company data shows most users “follow our workflow properly and obtain accurate results.”The FDA said one possible problem was related to the incorrect use of equipment that rapidly spins samples in preparation for processing. The agency’s letter tells lab workers to follow new instructions developed by the company for this step.A second issue relates to the software used on Thermo Fisher’s testing platform. FDA said labs must upgrade the software to a new version.Dr. Albert Ko of Yale’s School of Public Health said the potential accuracy problems have “pretty serious implications” given that Thermo Fisher’s test is used widely both in the U.S. and around the world to screen for coronavirus.The FDA statement did not provide any details on how many test results may have been affected by the problem.Lab tests are the backbone of U.S. screening for coronavirus, accounting for more than half of the roughly 750,000 tests developed daily. The tests look for traces of coronavirus’ genetic material in nasal swabs taken from patients.Thermo Fisher’s test was granted emergency use by the FDA in mid-March. The test runs on a large, automated machine used in hospital, government and commercial labs to look for diseases such as HIV, hepatitis and flu.The FDA has used its emergency powers to OK more than 200 tests for coronavirus since February. No test is perfect and all are expected to give at least a small percentage of false negatives and false positives.___The Associated Press Health and Science Department receives support from the Howard Hughes Medical Institute’s Department of Science Education.

President Donald Trump is expected to nominate State Department spokeswoman Heather Nauert to be his new ambassador to the UN, positioning a relatively inexperienced newcomer in one of the most high-profile positions in US diplomacy, according to an administration official and a second source.The announcement is expected to come on Friday, two officials say.In an administration rife with internal conflict and deeply distrustful of the UN, Nauert's nomination would place a less senior person at the international agency than outspoken current ambassador Nikki Haley, who reportedly sparred with other administration officials.The former Fox News host's precipitous rise since arriving at the State Department in 2017 sets the stage for a potentially tough Senate confirmation hearing, where Democrats will likely grill Nauert on her qualifications for the position.The nomination was first reported by Bloomberg News.  935

POWAY, Calif. (KGTV) -- Poway residents are expressing concern after Stoneridge Country Club closed without notice Wednesday morning.The club closed after voters defeated a measure Tuesday which would have rezoned the property to allow owner Michael Schlesinger to replace part of the club with 180 new condos.One member told 10News "I want the people of Poway to realize that it’s not just about losing golf. It’s about our home values and losing our history that we’ve had here for so long.”Her home sits directly adjacent to the course. She's concerned Schlesinger will stop maintaining the property, turning it into a major fire hazard.Several other residents also expressed worries about vagrants setting up camps on the vacant course and that overgrowth could lead to a spread of coyotes in the area.Those fears are stoked, the residents say, by what has happened at the Escondido Country Club, also owned by Schlesinger.The club has gone to waste in the four years since he made the decision to close it and Poway residents worry they're about to be victims of the same fate.Club members tell 10News there has been no communication from Stoneridge about the closure.Many members paid their 2018 dues in advance and fear Schlesinger will not refund their money.10News contacted a spokesperson for Schlesinger, who replied with a statement:"We are on day 2 of the process of closing a business that has been open for 60 years. Our employees were our first concern, and now we are just beginning to figure out details. On the issue of maintenance, the property will be secured for trespass and follow all appropriate, applicable guidelines." 1653

President Donald Trump on Tuesday again seized on what he called a "terrorist attack" in London to call for tougher anti-terror measures, even though the incident was still in the early stages of investigation."Another terrorist attack in London...These animals are crazy and must be dealt with through toughness and strength!," the US President tweeted.Metropolitan Police in London were investigating the event -- in which a car crashed into security barriers outside of the Houses of Parliament during rush hour Tuesday morning -- as a terrorist incident. The driver, a man in his late 20's, was arrested at the scene on suspicion of terrorist offenses. He was alone in the car and no weapons were recovered at the scene. 732
