Something extremely bogus is going on. Was tested for covid four times — COVID-19 testing

"Something extremely bogus is going on. Was tested for covid four times today. Two tests came back negative, two came back positive."

COVID-19 testing involves analyzing samples to assess the current or past presence of SARS-CoV-2, the virus that causes COVID-19 and is responsible for the COVID-19 pandemic. The two main types of tests detect either the presence of the virus or antibodies produced in response to infection. Molecular tests for viral presence through its molecular components are used to diagnose individual cases an

"Even once a test is working beautifully in the lab, it still faces an arduous journey to mass usage. The first challenge is to verify performance, because quality can vary. “It’s a Wild West out there for assay development,” says Catharina Boehme, chief executive officer of the Foundation for Innovative New Diagnostics (FIND), a non-profit group in Geneva that is collaborating with the World Health Organization and the University Hospitals of Geneva to assess hundreds of SARS-CoV-2 testing options. Most RT-PCR-based tests that FIND has evaluated perform just as well as the gold standard does, whereas antigen tests have so far fallen short of expectations, Boehme says. Another hurdle is scaling up the assays for mass production. Given this constraint, Boehme thinks it is unrealistic that all the new tests will be deployed before the end of the year — although a small number might be. But once they are available, they could work alongside the gold standard to push countries closer to the target of millions of tests per week — and prepare the world for the next pandemic."

"Guozhen Liu, a bioengineer at the University of New South Wales in Sydney, Australia, says that technologies such as CRISPR could be “a game changer” in the current pandemic. Thanks to their ability to quickly and precisely identify genetic snippets, these approaches “can find a needle in a haystack”, Liu says. They use different reagents from RT-PCR-based assays — useful when there are shortages of chemical supplies for standard tests — and they can be designed to target any pathogen. For example, a team led by computational biologist Pardis Sabeti at the Broad Institute created rubber ‘chips’ about the size of a smartphone that can search 1,000 samples for a single virus, or 5 samples for a panel of 169 viruses that are known to infect humans8."

"For some US allies, the fixation on words at a time when the international order was arguably facing its greatest challenge since the second world war encapsulated the glaring absence of US leadership. And that absence was illustrated just as vividly by news coverage of planes full of medical supplies from China arriving in Italy, at a time when the US was quietly flying in half a million Italian-made diagnostic swabs for use in its own under-equipped health system and Donald Trump was on the phone to the South Korean president pressing him to send test kits."
