On an April 6 phone call, members of a prestigious scientific committee told members of the White House Office of Science and Technology Policy there are issues with the availability and reliability of the antibody tests in the United States right now.
"In three words: Work in progress," said Dr. David Relman, a member of the National Academy of Sciences committee who was on the call.
A few days after the phone call, the NAS scientists wrote a letter to the White House frankly apprising them about the quality of antibody tests. Antibody tests check to see if a person has previously been infected with Covid-19, an indication that they've had the virus and now could be immune to it.
Results from antibody tests "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," according to the letter.
There are good tests in the midst of the bad ones, but they're not yet widely and easily available throughout the country.
It’s not entirely clear that having antibodies to Covid-19 means that you truly have immunity and won't get the disease again.
The White House Office of Science and Technology Policy did not respond to requests from CNN to describe what it learned on the April 6 call or how officials plan to use the information the scientists gave them.
Dr. Harvey Fineberg, chairman of the NAS committee, who was also on the phone call with the White House, said he felt that the White House officials paid close attention on the call.
"That's the brilliance of Kelvin Droegemeier, to elicit this kind of input and turn to the academics in the first place," Fineberg said, referring to the director of the White House policy office. "They're genuinely trying to widen their aperture for advice, and I think so far it's working."
