The U.S. capacity for SARS-CoV-2 testing is limited by several items, including the swabs used to collect patient specimens, but the supply of reagents has been front and center recently. Despite those concerns, several private test makers said they are quickly ramping up production, including Thermo Fisher Scientific Inc., of Waltham, Mass., which said it has enough supplies of all types on hand to provide 2 million reactions per week, a volume that should increase to 5 million per week in April.

The past week has seen a lot of movement in terms of tests to detect SARS-CoV-2, the virus that causes COVID-19. “It is notable that the diagnostics community is coming together in a way we have not seen in our 20 years covering this industry,” wrote William Blair analyst Brian Weinstein in a March 14 note. “Regulators, lab professionals, and manufacturers are all in a frenetic fury to try and get testing up and running, and we generally see a sense of ‘in it together’ playing out.”

The U.S. effort to deploy diagnostics for the novel coronavirus has been plagued by missteps by the CDC and the FDA from the outset, leading to delays and missed opportunities. The Trump administration declared a national emergency March 13, but concerns remain about how quickly the array of available tests can be conducted and whether there are enough testing supplies to handle the anticipated demand.

Thermo Fisher Scientific Inc., of Waltham, Mass., has made a bold play in the molecular diagnostics market, including infectious disease testing, with its proposed $11.5 billion acquisition of Qiagen NV, of Venlo, Netherlands. Word of the deal comes after reports late last year that named Thermo Fisher as a potential suitor for Qiagen. However, in late December, Qiagen said it had wrapped up a review of potential strategic alternatives and decided its standalone business plan represented the best opportunity for value creation.
