Liquid biopsy startup Grail Inc., of Menlo Park, Calif., has reeled in $390 million in a series D financing that included new investors Public Sector Pension Investment Board and Canada Pension Plan Investment Board. Prior investor Illumina Inc., of San Diego, also participated in the round, as well as two unidentified backers.

As states in the U.S. move past the initial push for tests to identify active COVID-19 infections, antibody tests are ramping up quickly to aid in disease surveillance and return-to-work screenings. The rush has spurred an explosion in serology tests, many hastily developed and of questionable value. However, as the pandemic enters its third month, some companies are offering high-accuracy tests with validated results.

The challenges to deploy diagnostic and surveillance testing for the COVID-19 pandemic will persist at least until a vaccine is ready if not well beyond that milestone. The state of COVID-19 testing as a regulated sector is a complex intersection of new and old technologies, questionable accuracy, availability hurdles, supply chain interruptions and problems with interpretation of results.

The COVID-19 pandemic has shaken the world – and the face of diagnostics. In a matter of weeks, a host of companies has worked to develop tests to find those patients who currently have the disease, as well as those who have developed antibodies.

The U.S. FDA continues to modify its emergency use authorization (EUA) policy for testing for the SARS-CoV-2 virus, although workplace testing is still on the agency’s to-do list. The FDA’s Tim Stenzel noted on a May 6 briefing that serological tests for antibodies must now demonstrate an overall sensitivity of 90% and overall specificity of 95%, a set of standards that might challenge some tests that are available under the EUA policy.

PARIS – In the wake of the news that Swiss group Roche Holding AG received an emergency use authorization from the U.S. FDA as well as a CE-IVD certification for the Elecsys Anti-SARS-CoV-2 serology test to detect antibodies in people previously exposed to SARS-CoV-2 that causes the COVID-19 disease, the company unveiled its plans for the launch of the product.

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.
