Cabin fever is emerging as a side effect of the novel coronavirus, or more accurately, the social distancing measures meant to keep COVID-19 at bay.

But some doctors are now questioning the quality of available tests, which Deborah Birx, the coordinator of the White House coronavirus task force, has called "critical."

In a letter to the White House, scientists from the National Academy of Sciences said the results "should be viewed as suspect until rigorous controls are performed and performance characteristics described, as antibody detection methods can vary considerably, and most so far have not described well-standardized controls."

Their concerns come as some countries consider issuing “immunity passports” that indicate whether a person is immune to COVID-19 and would allow them to resume certain activities.

Other members of the White House coronavirus task force, including Anthony Fauci, director of the National Institute of Allergy and Infectious Diseases (NIAID), have also made the connection between these tests and the loosening of prevention measures, including allowing people to return to school and work.

“Within a period of a week or so, we’re going to have a rather large number of tests that are available,” Fauci told CNN on April 10. Later that day, he told MSNBC that he expects a “real degree of normality” by the November elections.

"The antibody test says you were infected and if you're feeling well, you've very likely recovered," Fauci said. "As we look forward, as we get to the point of at least considering opening up the country as it were, it's very important to appreciate and to understand how much that virus has penetrated society."

Serology tests identify antibodies the immune system generates to fight COVID-19, either after having contracted the virus or receiving a vaccine. While the mere presence of COVID-19 antibodies does not guarantee immunity to the disease, labs can perform a neutralization assay on blood samples to determine whether the patient will be protected from future infections.

But this process can take up to five days and isn't simple. The Food and Drug Administration (FDA) has only authorized one test under an Emergency Use Authorization, but has allowed some developers to start distributing their tests without review. There have also been reports in the United Kingdom of false positive and false negative results, suggesting there are still flaws with the tests that have been developed.

"In three words: Work in progress," David Relman, a member of the National Academy of Sciences committee who was on the call, told CNN. Scott Becker, CEO of the American Public Health Lab Association, described some of the tests on the market as "crappy" to CNN.

Since then, Becker told CNN, the FDA has started to review the tests that are currently on the market. Still, you don’t need to rush out the door to get tested. For now, follow your local stay-at-home guidance and wait for further updates from your local government and public health officials.
