The role of diagnostic and surveillance testing in the COVID-19 pandemic is unquestionably critical, but the volume and type of tests needed to bring the economy back online is complex. Susan Van Meter, director of Advamed Dx, said on an April 22 press briefing that while molecular and serological tests will continue to play a vital role, “we’re going to see millions of antigen tests available in the coming weeks,” a development that will prove crucial in efforts to restore normal economic activity.

The COVID-19 pandemic has moved rapidly over the past few weeks, and Ortho Clinical Diagnostics Inc. is doing its part to help during the crisis. To that end, the Raritan, N.J.-based company has worked to successfully secure an emergency use authorization (EUA) for its total antibody assay for COVID-19, the Vitros Immunodiagnostic Products Anti-SARS-CoV-2 total reagent pack and calibrators.

HONG KONG – South Korea’s Osang Healthcare Co. Ltd. became the first Korean company to receive the U.S. FDA’s emergency use authorization (EUA) for its COVID-19 test kit. In a letter dated April 18, 2020, the FDA informed Osang of its authorization for the company’s Genefinder COVID-19 Plus Realamp Kit.

Gaithersburg, Md.-based startup Hememics Biotechnologies Inc. is partnering with the U.S. Biomedical Advanced Research and Development Authority (BARDA) to develop a rapid, Bluetooth-connected, point-of-care (POC) test for COVID-19. Designed for use in both field and traditional settings, the test detects SARS-CoV-2 and related antibodies from nasal swabs and whole blood, delivering results in a minute or less.

Despite challenges associated with the ongoing COVID-19 pandemic, Abbott Laboratories saw its first-quarter revenue beating expectations, coming in at $7.73 billion vs. an expected $7.44 billion. Cowen’s Josh Jennings highlighted this result, adding in a note that while there are challenges for nondiabetes medical devices and core diagnostics, areas including diabetes, nutrition, the established pharmaceuticals division and COVID-19 testing shined.

An April 15 U.S. FDA stakeholder call revisited several themes of interest in connection with diagnostics for the COVID-19 pandemic. However, Tim Stenzel, director of the agency’s Office of In Vitro Diagnostics and Radiological Health, said that while the agency has not yet authorized a home sample collection kit, “we do think it’s going to happen very soon.”

The collection of nasal and throat swab samples to detect the presence or absence of the novel coronavirus SARS-CoV-2 has proven problematic on a few fronts, particularly in the U.S. The swabs themselves often have become scarce and difficult to obtain, while health care workers are routinely risking their own health commonly in the absence of proper protective equipment. In addition, sampling difficulties have largely been blamed for a very high false negative rate that could be as much as 25%.

The age of molecular testing for the COVID-19 pandemic is still with us, but the emphasis in the months ahead will be on serological testing as a quicker, more useful mass testing alternative. However, test developers have a number of hurdles to overcome in devising these serological tests, including that antibodies for the virus’s antigens emerge at different times in the disease cycle, just one of several challenges that have to be met in the effort to bring the SARS-CoV-2 virus to heel.

The U.S. FDA’s routine guidance agenda may be badly disrupted by the COVID-19 outbreak, but the agency continues to pump out guidances and emergency use authorizations (EUAs) directed to the pandemic. While the FDA has included only one serological test under the diagnostic EUA paradigm, Rep. Diana DeGette penned a letter inquiring into when the agency intends to move more decisively on serological tests, arguing that the absence of action on this front endangers the nation’s economic health as well as the public’s health.
