With rates of preeclampsia skyrocketing, the U.S. FDA’s510(k) clearance of Roche Holding AG’s Elecsys test for preeclampsia offers some hope of reducing the number of women and infants who die or experience life-long consequences from the development of dangerously high blood pressure during late pregnancy and in the days immediately following delivery.

Anbio Biotechnology Ltd. launched the Anbio AF-100S, an automated, compact and affordable fluorescent immunoassay (FIA) solution that it hopes will transform the field of clinical diagnostics and empower healthcare providers. The AF-100S FIA is a handheld point-of-care immunodiagnostic solution that provides rapid, accurate and reliable results for a wide range of analytes.

Quidel Corp. reported a definitive agreement to acquire Ortho Clinical Diagnostics Holdings plc in a nearly $6 billion deal expected to close in the first half of 2022. The $24.68 per share offered by Quidel represents a nearly 25% premium over Ortho’s closing price as of Dec. 22. Quidel will also assume $2 billion in debt. In addition, Laboratory Corp. of America Holdings (Labcorp) said it would acquire Baltimore-based Personal Genome Diagnostics Inc., which offers a portfolio of genomics-based liquid biopsy and tissue-based diagnostic products, for $450 million in cash at closing plus up to $125 million contingent on achieving specific performance milestones. That deal is also expected to close in the first half of 2022, pending approval by both companies’ shareholders.

As the Omicron variant of COVID-19 sweeps across the globe, the Biden administration has announced a program to purchase 500 million rapid antigen tests to help slow the pandemic. The news comes at an especially critical time, given the increased transmissibility of the Omicron variant, but the promised volume is unlikely to be achieved by the first day of January 2022.

The U.S. National Institutes of Health (NIH) has waded into the controversial question of the respective roles of rapid antigen and polymerase chain reaction (PCR) tests for detection of the SARS-CoV-2 virus, a question that roiled relations between the FDA and public health experts. According to NIH, three rapid antigen tests administered at three-day intervals offer the same level of sensitivity as PCR, a finding that will likely make itself felt in future communicable disease outbreaks.

Non-clinical testing for the SARS-CoV-2 virus has been a major goal for regulators across the globe for months. Emergency use authorization (EUA) was just granted by the FDA is for the Quidel Quickvue COVID-19 test, an at-home antigen test with a turnaround time of 10 minutes. It’s the latest in a series of approvals of home tests and collection kits that promises to help control the pandemic.

The May 12 Senate hearing regarding the COVID-19 pandemic included the usual conversations about contact tracing, but Anthony Fauci, director of the National Institute of Allergy and Infectious Diseases, said he is “cautiously optimistic” that one of the vaccines currently in trial in the U.S. will work, but that it is unlikely a vaccine will be ready by September 2020. In contrast, Assistant Secretary for Health Brett Giroir said testing capacity may reach 50 million tests per month by that time, thanks in part to the fact that antigen testing is now part of the FDA’s emergency use authorization mechanism.

The U.S. FDA has issued an emergency use authorization (EUA) for an antigen test for the SARS-CoV-2 virus from Quidel Corp., of San Diego, that is more readily deployed than other diagnostic tests for the pathogen. Quidel’s offering can be used at the point of care (POC) and as a lab test.

Several companies have reported quarterly results over the past couple of days, and those offering testing for COVID-19 have seen impressive numbers. Standing out was San Diego-based Quidel Corp., whose numbers caught the attention of William Blair’s Brian Weinstein. Indeed, its $174.7 million in revenue far exceeded his organization’s estimate of $160 million, driven by influenza.
