FDA authorizes first T cell-based test to detect prior SARS-CoV-2

(HealthDay)—The T-Detect COVID Test, a T cell-based test that helps to identify individuals with recent or prior severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection, was granted emergency use authorization, the U.S. Food and Drug Administration announced Friday. The next-generation sequencing-based test analyzes DNA sequences to identify those with an adaptive T cell immune response

New COVID-19 RNA test gives accurate results within minutes

University of Birmingham researchers have invented a COVID-19 test that reduces testing time from 30 minutes to under five, and delivers accurate results. The method is described in a preprint paper (yet to be peer-reviewed) published on MedRxiv, where the researchers also demonstrate the rapidity and sensitivity of their method using patient sample RNA provided

Researchers collaborate on universal antibody test for COVID-19

Researchers with the U.S. Army Futures Command are part of a team that tested alternative ways to measure COVID-19 antibody levels, resulting in a process that is faster, easier and less expensive to use on a large scale. Their method holds promise for accurately identifying potential donors who have the best chance of helping infected

Global trial to test whether MMR vaccine protects front-line health-care workers against COVID-19

An international research network of physicians and scientists is launching a clinical trial to evaluate whether the vaccine for measles, mumps and rubella (MMR) can protect front-line health-care workers against infection from SARS-CoV-2, the virus that causes COVID-19. The trial aims to enroll up to 30,000 health-care workers globally. Washington University School of Medicine in

Frequently used serology test may not detect antibodies that could confirm protection against reinfection of COVID-19

Two different types of detectable antibody responses in SARS-CoV-2 (COVID-19) tell very different stories and may indicate ways to enhance public health efforts against the disease, according to researchers at The University of Texas MD Anderson Cancer Center. Antibodies to the SARS-CoV-2 spike protein receptor binding domain (S-RBD) are speculated to neutralize virus infection, while

Brazil to help test Oxford coronavirus vaccine

An experimental vaccine against the new coronavirus developed at the University of Oxford will be tested from mid-June in Brazil, the first country outside Britain to take part in the study, researchers said Wednesday. The vaccine will be tested in Brazil on 2,000 volunteers, who will be recruited starting this week, said the Federal University

Your SMARTPHONE could soon test coughs and sneezes for coronavirus

Could your phone diagnose you with COVID-19? Quarter-size sensor attached to your device’s charging port could test spit from your coughs and sneezes Researchers have developed a coronavirus sensor that can plug into the charging port of a smartphone  The sensor contains single-strand piece of DNA that looks for a specific combination of proteins  The

I was the family guinea pig for a new Covid antibody test

‘I was the family guinea pig for a new Covid antibody test’: SUE REID and SIMON WALTERS undergo coronavirus tests Here’s how to help people impacted by Covid-19 Antibody tests, which reveal whether you’ve had Covid-19, have been hailed as the way out of lockdown and safely getting people back to work.  With one of the

In random test of 500 in Afghan capital, one-third has virus

One-third of 500 random coronavirus tests in Afghanistan’s capital came back positive, health officials said Sunday, raising fears of widespread undetected infections in one of the world’s most fragile states. Neighboring Iran, meanwhile, said it would reopen schools and mosques in some locations, even though the nation has been the regional epicenter of the pandemic

New blood test for prostate cancer could help monitor patients

New blood test for prostate cancer could help monitor patients without invasive procedure and would reveal if they need urgent treatment Prostate cancer is most common among UK men with 50,000 diagnosed a year Study published in Journal of Clinical Investigation offers hope of a blood test At present the cancer is diagnosed through physical
