The future of coronavirus testing in the U.S.: at work, at home and in church
There are still unanswered questions about the accuracy of some COVID-19 tests, the prevalence of antibodies among Americans, and whether those antibodies provide the kind of immunity safety net needed to protect people from future infection.
The testing process for COVID-19 in the U.S. has been troubled from the start. The test kits designed and shipped by the Centers for Disease Control and Prevention in early February to public health laboratories had flawed components that “may be the result of a design and/or manufacturing issue or possible contamination,” a CDC spokesperson said in an email. The Department of Health and Human Services, which oversees the CDC, is conducting an assessment, he added.
In fact, a new process is under way at Walmart Inc. WMT, +1.99% testing sites. Individuals drive in, receive a swab from a health care worker, roll up the car window, and that worker observes them using the nasal swab themselves to collect the sample, according to comments made by Quest Diagnostics Inc. DGX, +6.49% CEO Steve Rusckowski during an earnings call on Wednesday.
At the same time, antibody testing has been called a “game-changer” in efforts to safety reopen the economy.
