FDA Authorizes First Covid-19 and Flu Combination Test for Use with Home-Collected Samples

The U.S. Food and Drug Administration authorized the first diagnostic test for at home collection of patient samples to detect both Covid-19 and influenza A and B (flu). The FDA authorized Quest Diagnostics RC Covid-19 +Flu RT-PCR Test for prescription use with the Quest Diagnostics Self-Collection Kit for Covid-19 +Flu by individuals who are suspected of respiratory viral infection consistent…

News • New gargle test

Mass spectrometry to improve Covid testing

A UK biotech laboratory has used mass spectrometry in a new approach to coronavirus testing. MAP Sciences developed a gargle test, which collects samples from the back of the throat, and avoids the unpleasant sensation of the current PCR (polymerase chain reaction) swab tests. From there, the sample is tested for coronavirus using mass spectrometry (MS) with high levels of accuracy.

News • False positive results

Accuracy of rapid covid test may be lower than previously suggested

The accuracy of a rapid finger-prick antibody test for SARS-CoV-2, the virus responsible for covid-19 infection, may be considerably lower than previously suggested, finds a study published by The BMJ. The results suggest that if 10% of people given the test had previously been infected, around 1 in 5 positive test results would be incorrect (false positive results). These conclusions contrast…

News • Using virus particles in exhaled breath

New SARS-CoV-2 test to deliver results in under 5 minutes

Research and innovation hub Imec announced that it has started developing a groundbreaking SARS-CoV-2 test. Unlike current approaches (using blood, saliva, or a nasopharyngeal swab), the new test will identify SARS-CoV-2 virus particles in a person’s exhaled breath. The solution promises the accurate identification of a contagious case in less than five minutes.

News • Testing strategy re-evaluated

COVID-19 testing at random? Here's a better idea

As COVID-19 infections begin to rise again, a novel testing strategy proposed by researchers at the University of Oxford at the start of the pandemic has become urgent once again. The strategy aims to bring the virus’s reproduction number (‘R’) down to below 1, by concentrating testing resources on particular groups in the population that are most likely to spread the infection to others,…

News • Review sheds doubt

Major flaws in evidence base for COVID-19 antibody tests found

Major weaknesses exist in the evidence base for COVID-19 antibody tests, finds a review of the latest research published by The BMJ. The evidence is particularly weak for point-of-care tests (performed directly with a patient, outside of a laboratory) and does not support their continued use, say the researchers. Serological tests to detect antibodies against COVID-19 could improve diagnosis and…

SARS-CoV-2 IgG antibody test receives FDA Emergency Use Authorization

Beckman Coulter announced that its Access SARS-CoV-2 IgG assay has received Emergency Use Authorization (EUA) from the U.S. Food & Drug Administration (FDA). Beckman Coulter has already shipped tests to more than 400 hospitals, clinics and diagnostics laboratories in the U.S., and has begun distribution of the new antibody test globally to countries that accept the FDA EUA and CE Mark. The…

News • UK experts raise concerns

COVID-19 antibody tests: Not a game-changer after all?

A group of senior clinical academics and physicians are concerned about the rapid roll out of COVID-19 antibody testing in England and are publicly questioning how good the tests are - or even what they mean. In a letter to The BMJ, they argue that there is currently no valid clinical reason for large scale testing, test performance has not yet been adequately assessed, and testing risks…

Scientists on Standby portal to support COVID-19 testing recruitment

Scientists on Standby has been rapidly conceptualised and launched in response to the COVID-19 crisis and in anticipation of the increasing pressure on UK diagnostic testing laboratories and facilities in the coming weeks and months. The portal enables scientists with relevant skills and experience to volunteer their time, expertise and support for COVID-19 screening and testing.

A more reliable way to early detect lung tumours

People who are at high risk of developing lung cancer, such as heavy smokers, are routinely screened with computed tomography (CT), which can detect tumors in the lungs. However, this test has an extremely high rate of false positives, as it also picks up benign nodules in the lungs. Researchers at the Massachussetts Institute of Technology (MIT) have now developed a new approach to early…

Coronavirus antibody test in development

In response to the global COVID-19 pandemic, Beckman Coulter announced that it is developing assays to identify IgM and IgG antibodies to the coronavirus or SARS-CoV-2. The assays will be designed for use on any of its high-throughput Access family of immunoassay systems, including the Access 2 and DxI series installed globally. Research has shown that after infection with SARS-CoV-2, viral…

World’s fastest DNA testing method created

A group of scientists from Vilnius University have developed the world’s fastest DNA testing method, reducing DNA testing costs by 90%. It identifies changes in chromosomes, genes, or proteins to determine a genetic condition or eliminate the chance of the formation or passing on of a gene-based disorder amongst humans and animals. At present, the sole method of genetic testing is the DNA…

Heat it and read it

You’re sweating and feverish and have no idea why. Fortunately, Sandia National Laboratories scientists have built a device that can pinpoint what’s wrong in less than an hour. Unlike most medical diagnostic devices which can perform only one type of test — either protein or nucleic acid tests — Sandia’s SpinDx can now perform both. This allows it to identify nearly any cause of…

Vitamin D testing: LC-MS outperforms immunoassays

In recent years, clinicians have increasingly focused on vitamin D deficiency. Studies show that previous reference values – particularly for Vitamin D3 – were most probably set too high. Liquid chromatography with mass spectrometry (LC-MS) can help achieve more precise measurements of vitamin D levels than previously established immunoassay procedures, explains Dr Torsten Binscheck-Domass,…
