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.

PORT-AU-PRINCE, Haiti (AP) — Tropical Storm Marco is swirling over the Gulf of Mexico heading for a possible hit on the Louisiana coast as a hurricane Monday. Meanwhile, Tropical Storm Laura has knocked utilities out as it batters Hispaniola, following a track forecast to take it to the same part of the U.S. coast later in the week, also as a hurricane. It would be the first time two hurricanes appear in the Gulf of Mexico simultaneously, according to records dating to at least 1900.On Saturday, the storms dumped rain on Puerto Rico and Hispaniola, while the other swept into the gulf through the gap between Cuba and Mexico's Yucatan Peninsula.A hurricane watch has been issued for the New Orleans metro area, which Hurricane Katrina pummeled in August 2005. 773

President Donald Trump falsely claimed Saturday that the New York Stock Exchange re-opened the day after the September 11, 2001, terrorist attacks in an effort to justify holding a rally on the same day that a mass shooting occurred at a synagogue in Pittsburgh.Speaking at a planned campaign rally in Illinois, Trump said he had weighed whether to cancel his rally as well as a speech at an agricultural convention earlier in the day in Indianapolis, Indiana, but ultimately decided against it, saying such a move would amount to giving the killer an edge. He compared his decision to continue with the rally to reopening the NYSE after the September 11 attacks, something that did not happen."And with what happened early today -- that horrible, horrible attack in Pittsburgh -- I was saying maybe I should cancel both this and that," Trump said, referring to the rally and his earlier appearance at the agricultural convention. "And then I said to myself, I remember Dick Grasso, a friend of mine, great guy. He headed up the New York Stock Exchange on September 11. And the New York Stock Exchange was open the following day. He said -- and what they had to do to open it you wouldn't believe. We won't even talk to you about it. But he got that exchange open." 1273

POWAY, Calif. (KGTV) - The city of Poway is applying for a 2 million dollar FEMA grant to take down hazardous trees along Espola and Twin Peaks Roads. The trees are considered a fire hazard on a popular fire evacuation route. Wildfire is a major concern in Poway. Twelve years ago, the Witch Creek Fire destroyed 90 homes. Four years earlier, driven by Santa Ana winds, the Cedar Fire roared through Poway destroying 53 homes.Adrian Burfield drives Twin Peaks every day and says a lot of trees need to come down.Adrian Burfield says, “It’s long overdue. Some of the trees are leaning. I just drive by there and see future problems. So yeah I’m glad to see it happen.”The application deadline is April 18th, and they will know something by the end of this year.If they get approved, the trees will start coming down next Spring. 838

President Donald Trump said Tuesday that his pick to lead the Department of Veterans Affairs, Dr. Ronny Jackson, "is one of the finest people I have ever met" but acknowledged he lacks experience in running a government agency."There's a lack of experience," he said.Trump said he hadn't heard particular allegations against Jackson but defended him and said he was being unfairly treated by the press and Democrats."I told Admiral Jackson just a little while ago, what do you need this for? This is a vicious group of people, they malign ... what do you need it for?" the President said he asked."He's an admiral, he's a great leader, and they question him for every little thing," Trump said.But he said he would leave it up to Jackson whether to continue pursuing confirmation."He is a high-quality person. It's totally his decision. So he'll be making a decision," he said. "I don't want to put a man through a process like this. It's too ugly and too disgusting."Trump said if he was Jackson making the decision, he would step aside."If I were him, I wouldn't do it," Trump said.  1098
