The capacity of U.S. medical providers and testing capacity for the unfolding COVID-19 pandemic continues to be sorely tested. But there is now a new route for people to pursue serological testing to detect who has already been exposed to the SARS-CoV-2 virus.

HONG KONG – Israeli companies have produced some promising med-tech solutions for COVID-19, and the artificial intelligence space is turning out to be a particularly strong area of expertise for that tiny but mighty nation. One of the four health maintenance organizations (HMO) in Israel, Maccabi Healthcare Services, has deployed a new AI-powered algorithm that identifies individuals estimated to be at the highest risk of severe COVID-19 complications due to pre-existing conditions and other health factors.

LONDON – With COVID-19 infection varying in severity from asymptomatic to lethal the search is now underway for biomarkers to predict which patients are most at risk of suffering severe disease. As one possibility, Menarini Silicon Biosystems (MSB) is using its Cellsearch liquid biopsy technology to capture and count circulating endothelial cells. Meanwhile, Oxford Biodynamics plc is applying its Episwitch platform to find prognostic and predictive epigenetic markers.

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.
