Testing tool can quickly distinguish between viral and bacterial infections

When patients complain of coughing, runny nose, sneezing and fever, doctors are often stumped because they have no fundamental tool to identify the source of the respiratory symptoms and guide appropriate treatments. That tool might finally be on its way. In a study proving feasibility, researchers at Duke Health showed that their testing technology can accurately distinguish between a viral […]

Mass home COVID testing is misguided and unlikely to reduce transmission, warn experts

Encouraging self-testing at home twice a week for all adults in England, and soon Scotland, is a misguided policy, unlikely to reduce transmission, warn public health experts in The BMJ today. “The priority continues to be improvement of the testing programme for everyone with symptoms no matter how minor or non-specific and all their contacts” Encouraging self-testing at home twice […]

Pill testing won’t give people a ‘green light’ to use drugs

New research from Edith Cowan University (ECU) has found pill-testing services at Western Australian music festivals would not change people’s intention to take ecstasy if they had not used the drug before, a common argument used by opponents of pill testing. The study also found people who planned to take ecstasy at the festival reported they would not consume more […]

3D lab skin for chemicals testing, research and repair

A model system that recreates full-thickness human skin should allow more effective testing of pharmaceuticals and cosmetics, while avoiding the need for animal tests. The system effectively models the development, cellular structure and barrier properties of skin. This should also make it suitable for analyzing disease states and wound repair processes. Another potential use is as a substrate for repairing […]

Rapid antigen testing for COVID-19: Piecing the puzzle together

A new study from Boston Children’s Hospital and the Massachusetts Department of Health compared one of the latest rapid antigen tests for COVID-19—the Abbott BinaxNOW—with a highly accurate PCR test in a high-volume, drive-thru testing environment. They found that the rapid test detected almost all adults who tested positive by PCR if they had had symptoms lasting seven days or […]

MicroRNA testing of healthy kids could provide a window on future heart and kidney health

Molecules called microRNAs (miRNAs) that are measurable in urine have been identified by researchers at Mount Sinai as predictors of both heart and kidney health in children without disease. The epidemiological study of Mexican children was published in February in the journal Epigenomics. “For the first time, we measured in healthy children the associations between urinary miRNAs and cardiorenal outcomes, […]

Chip simplifies COVID-19 testing, delivers results on a phone

COVID-19 can be diagnosed in 55 minutes or less with the help of programmed magnetic nanobeads and a diagnostic tool that plugs into an off-the-shelf cell phone, according to Rice University engineers. The Rice lab of mechanical engineer Peter Lillehoj has developed a stamp-sized microfluidic chip that measures the concentration of SARS-CoV-2 nucleocapsid (N) protein in blood serum from a […]

Novel pooled testing strategies can significantly better identify COVID-19 infections

A new approach to pooled COVID-19 testing can be a highly effective tool for curbing the SARS-CoV-2 pandemic, even if infections are widespread in a community, according to researchers at Harvard T.H. Chan School of Public Health and the Broad Institute of MIT and Harvard. Simple pooled testing schemes could be implemented with minimal changes to current testing infrastructures in […]
