Roche Holding AG, of Basel, Switzerland, has garnered U.S. FDA authorization for emergency use of a test to determine whether people have been infected with the novel coronavirus fueling the COVID-19 pandemic. The Swiss health care giant, which also makes molecular tests to detect active COVID-19 infection, claims its Elecsys Anti-SARS-CoV-2 antibody test accurately identifies COVID-19 antibodies in the blood 100% of the time, 14 days post-infection.

Researchers in Guangzhou, China, have developed a nanoparticle-based lateral flow immunoassay that quickly and accurately detects antibodies to the SARS-CoV-2 virus that causes COVID-19. The current test, which works in a similar manner to a pregnancy test, detects IgG antibodies in blood in less than 10 minutes. A proof-of-concept study appeared in Analytical Chemistry this week.

PERTH, Australia – Australia is taking several measures to increase diagnostic testing for COVID-19 and rolling out a national surveillance app as it prepares to relax social distancing measures and get back to work.

Bio-Rad Laboratories Inc. has launched its SARS-CoV-2 Total Ab test, which is a blood-based assay to identify all the antibodies that are developed by the human body in response to the novel coronavirus SARS-CoV-2. Companies have been racing to offer serological tests that work to detect the antibodies developed during a COVID-19 infection that remain present in the blood after the initial infection clears.

KARACHI, Pakistan – With limited resources, a growing outbreak and a tech savvy population, Pakistan is reaching into a diverse bag of tricks to find ways to battle COVID-19. Part of these efforts include at least one artificial intelligence (AI)-based diagnostic product as well as molecular diagnostic assays.

Hologic Inc., of Marlborough, Mass., is introducing another tool to help combat COVID-19, revealing the impending launch of a new Aptima molecular assay to detect the SARS-CoV-2 virus that will run on its Panther system. The company expects to be able to provide its lab customers with about 3 million Aptima tests next week. In addition, it anticipates producing about 1 million tests a week starting late next month.

The COVID-19 pandemic has gripped the conversation regarding diagnostic and surveillance testing, but stakeholders nonetheless saw fit to populate the docket for the FDA’s proposal to down-classify tests for the human immunodeficiency virus (HIV) to class II. One of the themes of the feedback was that the proposal excludes a few key items, such as quantitative nucleic acid tests and testing for viral load monitoring, leaving the FDA with some difficult decisions to make.

TORONTO – Within a week of completing clinical trials the chest radiography AI tool developed by Vancouver, B.C.-based 1Qbit Inc. has been given the all-clear from Health Canada for deployment across the country. The XrAI was originally developed to better identify patients with respiratory illness including SARS, pneumonia and tuberculosis (TB), but then in February was tested on a publicly available data set of COVID-19 X-ray images.
