When Congress reconvenes in January, the lengthy docket of action items is expected to include proposed solutions to the years-long conundrum over how to regulate laboratory developed tests (LDTs). The FDA touched off the issue in 2014 when it proposed regulating “high-risk” LDTs along the lines of Class III medical…

A novel lab-on-a-chip infection test developed by researchers at Imperial College London could provide a less expensive, faster and portable diagnostic tool. Dubbed TriSilix, the chip performs a miniature version of polymerase chain reaction (PCR) testing on bodily fluids, feces, or environmental samples, according to the scientists who published a…

More than one-in-three COVID-19 patients present with neurological symptoms such as loss of smell and taste, headache, fatigue, nausea, and vomiting in addition to acute cerebrovascular disease and impaired consciousness. These symptoms, observed in a large portion of individuals with COVID-19, suggest that SARS-CoV-2 very likely penetrates the central nervous…

A large study carried out by researchers at University College London suggests that none of the recorded mutations in SARS-CoV-2 increase its transmissibility, contrary to claims from other researchers. Viruses all mutate over time, but some do this faster than others. Most mutations will not have a noticeable effect, but…
