“Today’s authorization is a major milestone in diagnostic testing for COVID-19. The test detects fragments of proteins of the SARS-CoV-2 virus from a nasal swab sample from any individual 2 years of age or older. The Ellume COVID-19 Home Test is a rapid, lateral flow antigen test, a type of test that runs a liquid sample along a surface with reactive molecules. Food and Drug Administration issued an emergency use authorization (EUA) for the first over-the-counter (OTC) fully at-home diagnostic test for COVID-19. The simple answer is yes, and they shouldn’t be used.Today, the U.S. She added that data collected by labs from PCR results are fed back to national health authorities daily, with governments then choosing how best to share the findings with other countries and with the World Health Organization. That’s actually how the Omicron variant was identified.” In our tests we look for an S Gene dropout which is a key indicator to health authorities. Patel explained: “PCR tests can help us understand the virus better because different genes are targeted which makes them more sensitive and accurate. Testing has even helped identify new strains in the past. The good news is, experts believe tests will continue to work on future variants of the virus. Will tests continue to work on future strains? She added she believed that test providers across the globe, like her own, are continually trialing their tests on new mutations. McCormick added that so far there is no evidence of tests not working on COVID variants like Kraken. in 2022 with McCormick saying demand had been fairly consistent throughout the year. The company distributed more than 17 million tests in the U.K. He was echoed by Penny McCormick, CEO of MyHealthChecked and Bhavika Patel who is a technical advisor on the business’ advisory board. He added that the organization does “continuing surveillance”, with new clinical tests carried out as soon as a new strain is identified. Surescreen Diagnostics is a UK-based company that sent rapid antigen tests for COVID across the world, covering Europe, Australia and Latin America.Īndrew Wilcher, chief executive of the family-owned business, explained that thus far there have been “no issues” with their lateral flow tests detecting mutations. As the swap is amplified millions of times, this means the PCR tests is more sensitive because they are looked at in much more detail. This work is done when the sample is sent back to a laboratory. PCR tests collect a sample and then isolate genetic materials – not proteins – before amplifying them. Rapid flow antigen tests have been given out by the government or can be bought by individuals, who test themselves and then submit their results to public health bodies. Depending on the viral load of the patient – how many of the antigens they have – the line will show up more boldly or faintly. If a threshold of antigens is identified in the test’s cassette then it will show a positive line. Lateral flow tests look for antigens – a type of protein that sits on the surface of COVID cells.
