Despite Shortfalls And Delays, U.S. Testing Czar Says Efforts Are Mostly 'Sufficient'

Public health experts generally agree that, in spite of improvements, the U.S. still falls short on the testing needed to combat the COVID-19 pandemic.

The official who oversees the country's testing efforts however maintains the U.S. is doing well on testing now and will soon be able to greatly expand testing using newer, point-of-care tests that deliver quick results.

In an interview with NPR's Morning Edition, Admiral Brett Giroir pointed out the U.S. is currently conducting more than 700,000 tests a day. He argued that some parts of the country are already conducting enough tests to contain outbreaks.

"We know that in areas of the country right now that have appropriate mitigation, that the testing we have is sufficient. We know right now that the testing we have is dense enough that we can detect very sensitively where there's going to be a problem," the assistant secretary of health told NPR.

Nonetheless he said efforts are underway to increase testing. "We're going to expand testing probably two or threefold within the next couple of months," he said.

A recent analysis for NPR by Harvard researchers found that more than 1 million tests were needed to mitigate, or keep outbreaks from getting worse. Giroir said the U.S. is well on its way to this target.

"We're going to be over a million tests very soon. That's not even a question," Giroir said.

That same analysis also found some 4.3 million people would have to be tested daily to truly suppress the U.S. outbreak and begin to let life get back to normal. The latest numbers from Harvard found only 16 states and territories have reached the mitigation benchmark, and of those four are doing enough testing to suppress the virus.

Giroir pushed back on the notion that the U.S. was behind on reaching those criteria.

"Yes, we want to have more testing, more testing will be better. But right now, we're in a good place to tell us the information we need." Giroir said.

Giroir said the administration is surging testing in areas once again hit hard by COVID-19 outbreaks – including Phoenix, Baton Rouge and Jacksonville, Fla. – but that in many cases testing is adequate if other mitigation efforts are in place.

He emphasized the need for public health measures in addition to testing, including social distancing and wearing masks. "We need places that are in hot zones to close bars and to limit restaurants. And if we do those simple things, we can turn around the virus," he said.

Giroir is not the first person involved with the U.S. coronavirus effort to claim testing for the coronavirus is on track. Back in April, Vice President Mike Pence, who oversees the White House Coronavirus Task Force, claimed the U.S. had enough tests to begin reopening.

Since then, testing for the coronavirus has become more widespread. But there continue to be shortages in the supplies and the machines needed to get results.

Since cases started surging in June, labs have reported delays in getting results due to increased volume. In Washington D.C., for example, recipients of coronavirus tests may be asked to wait up to seven business days for results. Quest Diagnostics, one of the largest testing companies, said testing volumes have pushed wait times up to nearly a week.

Even Trump's former Chief of Staff, Mick Mulvaney has complained, claiming his son waited a week for his results.

Giroir acknowledged the growing wait times due to the "unprecedented demand."

"We want to decrease that time on average between three and four days across the country. But as you pointed out, some people are waiting five, six or seven days and we do want to get that down," Giroir told NPR's Steve Inskeep.

Delays in testing mean public health workers are not able to notify the contacts of people who test positive, and so people may unwittingly continue to spread the virus.

Giroir was bullish on the potential of newer testing technology to hugely expand the country's ability to test quickly. He said fast point-of-care tests can help solve the problem of overburdened laboratories and could help with reopening schools and businesses in the fall.

"Certainly by September, we expect to have 15 to 20 million point of care tests. That's as many tests as we're doing every month now," Giroir said, adding that the administration wants to see 100 million tests per month happening then.

These point-of-care — or antigen tests — do yield a much speedier result but as NPR has reported, they may miss up to 20% of infections.

Giroir also mentioned pooling, which saves resources by bundling samples from multiple people together. Pooled testing tends to lose effectiveness in areas with higher coronavirus infection rates. [Copyright 2020 NPR]
