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 railed against the Iran nuclear deal Tuesday, calling the Obama administration-negotiated deal as "insane" and "ridiculous" while seated next to French President Emmanuel Macron in the Oval Office.The outburst proved that a dinner of Dover sole and a glitzy military welcome could not paper over the two leaders' differences as they begin intensive talks on Iran and Syria.Trump offered scant assurances to Macron that he was reconsidering his pledge to exit the agreement."People know my views on the Iran deal," Trump said. "It was a terrible teal. It should have never been made."It was an auspicious start to Trump's inaugural state visit, which has been in the works for months. Earlier in the day, the two men put forward an elaborate show of friendship on the South Lawn, reviewing cordons of troops in formation and recalling the long history between the US and France.But moments later, Trump was putting to rest any notion he might be swayed on the Iran deal, which Macron hopes to salvage, perhaps by altering its terms."Iran seems to be behind everywhere there is a problem," Trump said in the Oval Office. "They're testing missiles. What is that all about?""What kind of a deal is this where it wasn't even discussed?" he added. 1272

President Donald Trump and Alec Baldwin engaged in a Twitter feud Friday morning after the President mocked the actor's impression of him on "Saturday Night Live.""Alec Baldwin, whose dying mediocre career was saved by his terrible impersonation of me on SNL, now says playing me was agony. Alec, it was agony for those who were forced to watch," Trump said on Twitter, at first misspelling Baldwin's name as "Alex" before fixing."Bring back Darrell Hammond, funnier and a far greater talent!" Trump said, referring to the former SNL cast member who formerly portrayed him.Baldwin, who made his debut on SNL as Trump during the 2016 campaign, quickly shot back."Agony though it may be, I'd like to hang in there for the impeachment hearings, the resignation speech, the farewell helicopter ride to Mara-A-Lago. You know. The Good Stuff. That we've all been waiting for," the actor tweeted.Next, he tweeted: "Looking forward to the Trump Presidential Library. A putting green. Recipes for chocolate cake. A live Twitter feed for visitors to post on. A little black book w the phone numbers of porn stars. You're in and out in five minutes. Just like..."  1166

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

President Donald Trump is visiting Kenosha, Wisconsin, which was the site of both peaceful protests and riots last week following the police shooting of Jacob Blake.The protests have mostly been peaceful in the city in the last few days. However, some politicians fear that Trump's visit could stoke embers of emotion and spark more violence in the nights to come.Trump's visit takes place against the wishes of both Wisconsin Gov. Tony Evers and Kenosha Mayor Kenosha Mayor John Antaramian — both Democrats — who say that emotions in the city are still too raw."We want everything to calm down," Antaramian said in a press conference on Monday. "We want to give people an opportunity to talk before the president comes into town."During press availability on Monday, Trump said it was important to visit the law enforcement agents and national guardsmen and thank them for bringing order to the city, adding that his visit could "increase love and respect for our country."Republican lawmakers in the state, including Rep. Bryan Steil, welcome the President's visit."Many men and women stood up to help provide that public safety in Kenosha, and the President is coming to say thank you," Steil said.While in Kenosha, Trump is not scheduled to visit Blake or his family. The President said Monday that he spoke with the family's pastor in the hopes of setting up a call with Blake and his family, but said the pastor requested a lawyer be on the line during the call, which he thought was "inappropriate."Instead, Trump will survey the damage in the city, tour an emergency operations center and participate in a "safety roundtable" before returning to Washington. During a press conference on Monday, Trump said he felt it was important to thank national guardsmen and police."I have to see the people that did such a good job for me," Trump said on Monday. 1867
