Goal of his foundation is to provide access to COVID-19 medical laboratory tests for first responders, as well as low-cost tests to the general public
Early in April, when many of the nation’s clinical laboratories were facing numerous challenges in their attempts to obtain adequate supplies for collecting, transporting, and testing for COVID-19, a Hollywood actor was funding his foundation and obtaining enough supplies for his foundation to offer access to COVID-19 testing to residents in his community of Malibu—as well as in other areas.
In many ways, local medical laboratories that offer COVID-19 tests are competing with actor/philanthropist Sean Penn’s Community Organized Relief Effort (CORE) foundation for the supplies they need to provide COVID-19 testing to the patients in their own communities. The non-profit organization says it is working with various healthcare providers to provide free coronavirus testing to first responders, and low-cost testing to the general public, in eleven cities and counties in California, Georgia, North Carolina, and Illinois.
In fact, the volume of COVID-19 testing CORE currently provides is large enough that The Hollywood Report published a story on June 3, titled, “How Sean Penn Made the Biggest COVID-19 Testing Site in U.S.” The article stated that, “In late May, Mayor Eric Garcetti announced the opening of a new COVID-19 testing site at Dodger Stadium in partnership with CORE, the Los Angeles Dodgers, Live Nation Entertainment, Red Rock Entertainment, and the Los Angeles Fire Department. Operated by CORE and LAFD, this site has capacity to test 6,000 residents a day free of charge––making it three times the size of any other location in L.A. County and said to be the largest testing site in the U.S.”
The Reporter did not make the distinction that the Dodger Stadium site is only collecting specimens. And, no news accounts of the CORE COVID-19 testing program names the clinical laboratories that CORE currently uses to perform the coronavirus tests for the specimens it collects.
CORE Partnered with Private Healthcare Provider Elevated Health
CORE first got underway in 2010 providing disaster relief following the catastrophic magnitude 7.0 earthquake in Haiti. It was known then as the Jenkins-Penn Haitian Relief Organization (J/P HRO). The foundation initiated its support of COVID-19 testing efforts in California in April, reported the Orange County Register (OCR). At that time, testing was much more limited than it is today and drive-thru testing in most areas in America was not available.
Elevated Health’s COVID Clinic website enables consumers to complete pre-test enrollment and payment before arriving at the drive-up testing site at the Westminster Mall.
“Right now, hospitals have very strict guidelines on who can be tested. Public health departments are overwhelmed and possibly underfunded. That’s where I’m trying to bridge the gap,” Matthew Abinante, DO, a doctor of osteopathy and Elevated Health’s founder and CEO, told the OCR.
The coronavirus test kits Elevated Health uses are made in China and were purchased from Georgia-based HealthTrackRx. According to Abinante, they are “FDA authorized, but not FDA approved,” reported the OCR.
Clinical laboratory leaders may be intrigued to see consumers waiting their turn at drive-through testing lines as they take COVID-19 diagnosis into their own hands. Sites like the one above run by Elevated Health at the Westminster Mall demonstrate that people are willing to patronize providers that serve their needs directly.

CORE Aims to Be a Model for Partnering in Testing
Though CORE’s COVID-19 testing relief efforts are no longer limited to Los Angeles County, that is where it all began. Specimen collection at drive-through sites for COVID-19 tests initially prioritized first responders and essential workers. CORE funds provided for a staff of 70 people at four of the 35 drive-thru specimen collection sites in LA, reported CBS Los Angeles(CBSLA).
CORE-funded services also made it possible for Los Angeles city employees—who were running the drive-thru specimen collection sites—to return to their primary jobs as emergency first responders, reported the Associated Press (AP).
“It’s something that we can adapt to very quickly with the training of the Los Angeles Fire Department initially. And we’re able to take all those firemen and put them back in to serve the people in the way that we need them to,” said Penn in the AP article.
At that time, city officials planned to perform 10,000 tests a day, Deputy Mayor Jeff Gorell, JD, told the LA Times. The City of Los Angeles purchased the tests and CORE covered the cost of staff, volunteers, and personal protective equipment (PPE), reported the LA Times.
“We have servers and people from the Peace Corps, actresses—a lot of people from the communities where the test site is. We’re trying to hire as much locally as possible,” Ann Lee, CORE’s Chief Executive Officer, told Business Insider.
CORE also partnered with the City of Malibu in western Los Angeles County to provide mobile COVID-19 testing services for the city’s 3,000 residents, first responders, and essential workers from April 6 to 17 at a testing site at Malibu City Hall.
“This is what I hope will be a model in terms of the government and community foundation partnerships that can be replicated not only in the city of Los Angeles and throughout California, but throughout the country,” Sean Penn (above at the COVID-19 drive-thru testing site in Malibu, Calif.), founder of CORE, told CBSLA. Since making that statement, CORE has gone on to partner with healthcare providers in three other states to provide coronavirus drive-thru specimen collection.

Should Drive-Through Testing Continue Post-Pandemic?
An April Dark Daily e-briefing reported on drive-thru COVID-19 specimen collection operations across 30 states. The e-briefing also noted that drive-thru collections protects medical laboratory professionals and emergency department staff from possible exposure to infectious agents.
It’s likely many industries—from education and retail to travel and restaurants—will be revamped as a result of the pandemic. Clinical laboratory leaders and pathologists will want to study the different approaches used to develop drive-through COVID-19 specimen collection; how some providers that ran them partnered with charitable organizations such as CORE; why drive-thru specimen collection appeals to consumers; and how it may improve phlebotomists’ safety and increase clinical laboratory business.
Questions remain, however, over how much of the funding will actually reach hospital and health system clinical laboratories
For many cash-strapped clinical laboratories in America, the second round of stimulus funds cannot come soon enough. Thus, lab leaders are encouraged by news that Congress’ $484-billion Paycheck Protection Program and Healthcare Enhancement Act (H.R.266) includes almost $11 billion that will go to states for COVID-19 testing. But how much of that funding will reach the nation’s hospital and health system clinical laboratories?
The Department of Health and Human Services (HHS) announced the new influx of money to the states on May 18. In a news release outlining the initiative, the HHS said the Centers for Disease Control and Prevention (CDC) will deliver $10.25 billion to states, territories, and local jurisdictions to expand testing capacity and testing-related activities.
To qualify for the additional funding, governors or “designee of each State, locality, territory, tribe, or tribal organization receiving funds” must submit to HHS its plan for COVID-19 testing, including goals for the remainder of calendar year 2020, to include:
“Number of tests needed, month-by-month to include diagnostic, serological, and other tests, as appropriate;
“Month-by-month estimates of laboratory and testing capacity, including related to workforce, equipment and supplies, and available tests;
“Description of how the resources will be used for testing, including easing any COVID-19 community mitigation policies.”
“As the nation cautiously begins the phased approach to reopening, this considerable investment in expanding both testing and contact tracing capacity for states, localities, territories, and tribal communities is essential,” said CDC Director Robert R. Redfield, MD, in the HHS statement. “Readily accessible testing is a critical component of a four-pronged public health strategy—including rigorous contact tracing, isolation of confirmed cases, and quarantine.” (Photo copyright: Center for Disease Control and Prevention.)
Funding Should Go Directly to Clinical Laboratories, Says ACLA
The American Clinical Laboratory Association (ACLA), argues the funding needs to go directly to clinical laboratories to help offset the “significant investments” labs have made to ramp up testing capacity during the pandemic.
“Direct federal funding for laboratories performing COVID-19 testing is critical to meet the continued demand for testing,” ACLA President Julie Khani, MPA, said in a statement. “Across the country, laboratories have made significant investments to expand capacity, including purchasing new platforms, retraining staff, and managing the skyrocketing cost of supplies. To continue to make these investments and expand patient access to high-quality testing in every community, laboratories will need designated resources. Without sustainable funding, we cannot achieve sustainable testing.”
Some States Are Increasing Testing, While Others Are Not
Since the first cases of COVID-19 were reported in January, the United States has slowly but significantly ramped up testing capacity. As reported in the Washington Post, states such as Georgia, Oklahoma, and Utah are encouraging residents to get tested even if they are not experiencing coronavirus symptoms. But other states have maintained more restrictive testing policies, even as their testing capacity has increased.
“A lot of states put in very, very restrictive testing policies … because they didn’t have any tests. And they’ve either not relaxed those or the word is not getting out,” Ashish Jha, MD, MPA, Director of the Harvard Global Health Institute, told the Washington Post. “We want to be at a point where everybody who has mild symptoms is tested. That is critical. That is still not happening in a lot of places.”
Meanwhile, Quest Diagnostics and LabCorp continue to expand their diagnostic and antibody testing capabilities.
On May 18, Quest announced it had performed approximately 2.15 million COVID-19 molecular diagnostic tests since March 9 and had a diagnostic capability of 70,000 test each day. The company said it expected to have the capacity to perform 100,000 tests a day in June.
LabCorp’s website lists its molecular test capacity at more than 75,000 tests per day as of May 22, with a capacity for conducting at least 200,000 antibody tests per day. Unlike molecular testing that detects the presence of the SARS-CoV-2 coronavirus, antibody tests detect proteins produced by the body in response to a COVID-19 infection.
As states reopen, and hospitals and healthcare systems resume elective surgeries and routine office visits, clinical laboratories and anatomic pathology groups should begin to see a return to normal specimen flow. Nonetheless, the federal government should continue to compensate laboratories performing COVID-19 testing for the added costs associated with meeting the ongoing and growing demand.
Report’s authors claim the US needs to be testing 20-million people per day in order to achieve ‘full pandemic resilience’ by August
Medical laboratory scientists and clinical laboratory leaders know that the US’ inability to provide widespread diagnostic testing to detect SARS-CoV-2—the novel coronavirus that causes the COVID-19 illness—in the early stages of the outbreak was a major public health failure. Now a Harvard University report argues the US will need to deliver five million tests per day by early June—more than the total number of people tested nationwide to date—to safely begin reopening the economy.
“We need to deliver five million tests per day by early June to deliver a safe social reopening,” the report’s authors state. “This number will need to increase over time (ideally by late July) to 20 million a day to fully remobilize the economy. We acknowledge that even this number may not be high enough to protect public health. In that considerably less likely eventuality, we will need to scale-up testing much further. By the time we know if we need to do that, we should be in a better position to know how to do it. In any situation, achieving these numbers depends on testing innovation.”
The report is the work of a diverse group of experts in economics, public health, technology, and ethics, from major universities and big technology companies (Apple, Microsoft) with support from The Rockefeller Foundation.
“This is the first plan to show operationally how we can scale up COVID-19 testing sufficiently to safely reopen the economy—while safeguarding fundamental American democratic principles of protecting civil rights and liberties,” Danielle Allen, PhD (above), Director of Harvard University’s Edmond J. Safra Center for Ethics, said in a statement that noted it was “in response to the US Department of Health and Human Service’s Report to Congress on its COVID-19 strategic testing plan.” (Photo copyright: Harvard University.)
Under Harvard’s Roadmap plan, massive-scale testing would involve rapid development of:
Streamlined sample collection (for example) involving saliva samples (spit kits) rather than deep nasal swabs that have to be taken by healthcare workers;
Transportation logistics systems able to rapidly collect and distribute samples for testing;
Mega-testing labs, each able to perform in the range of one million tests per day, with automation, streamlined methods, and tightly managed supply chains;
Information systems to rapidly transmit test results; and
Technology necessary to certify testing status.
“The unique value of this approach is that it will prevent cycles of opening up and shutting down,” Anne-Marie Slaughter, CEO of New America, said in the statement. “It allows us to mobilize and re-open progressively the parts of the economy that have been shut down, protect our frontline workers, and contain the virus to levels where it can be effectively managed and treated until we can find a vaccine.”
Is Expanding Clinical Laboratory Testing Even Possible?
But is such a plan realistic? Perhaps not. When questioned by NBC News about the timeline for “broad-based coronavirus testing” that was suggested as part of the Trump Administration’s three-phase plan to reopen the states, former FDA Commissioner Scott Gottlieb, MD, said, “We’re not going to be there. We’re not going to be there in May, we’re not going to be there in June, hopefully, we’ll be there by September.”
In recent weeks, however, US testing capabilities have improved. Quest Diagnostics, which had come under fire for its testing backlog in California, announced it now has the capacity to perform 50,000 diagnostic COVID-19 tests per day or 350,000 tests per week with less than a two-day turnaround for results. “Our test capacity outpaces demand and we have not experienced a test backlog for about a week,” Quest said in a statement.
CDC ‘Modifies’ Its Guidelines for Declaring a Person ‘Recovered’ from COVID-19
Furthermore, the CDC modified its guidance on the medical and testing criteria that must be met for a person to be considered recovered from COVID-19, which initially required two negative test results before a patient could be declared “confirmed recovered” from the virus. The CDC added a non-testing strategy that allowed states to begin counting “discharged” patients who did not have easy access to additional testing as recovered from the virus.
Under the non-test-based strategy, a person may be considered recovered if:
At least three days (72 hours) have passed since recovery, defined as resolution of fever without the use of fever-reducing medications;
Improvement in respiratory symptoms (e.g., cough, shortness of breath); and,
At least seven days have passed since symptoms first appeared.
For now, however, the focus will likely remain on testing for those who are infected, rather than for finding those who have recovered. As of May 30, the COVID Tracking Project reported that only 16,495,443 million tests had been conducted in the US, with 1,759,693 of those test showing positive for COVID-19. That’s closing in on the 10% “test-positivity rate” recommended by the WHO for controlling a pandemic, but it’s not quite there.
As testing for COVID-19 grows exponentially, clinical laboratories should anticipate playing an increasingly important role in the nation’s response to the COVID-19 pandemic.
Schwan’s concerns about inaccurate or unreliable COVID-19 serology tests were supported when the FDA issued more restrictive rules for these medical laboratory tests on May 4
During a conference call with investors about the company’s first-quarter results, Schwan said of the recently-launched COVID-19 antibody assays, “These tests are not worth anything, or have very little use,” according to reporting from Reuters and other publications. “Some of these companies, I tell you, this is ethically very questionable to get out with this stuff.”
On May 3, Roche announced that its own Elecsys Anti-SARS-CoV-2 antibody test for SARS-CoV-2, the coronavirus that causes the COVID-19 illness, had obtained an emergency use authorization (EUA) from the federal Food and Drug Administration (FDA). In its news release, Roche stated that “the serology test has a specificity greater than 99.8% and sensitivity of 100% (14 days post-PCR confirmation).”
In a separate interview with Bloomberg, Schwan said about antibody testing, “It is very important to pick the right test and then to validate those tests with enough patients.” He then returned to the issue of poor quality in some antibody tests for the SARS-CoV-2 virus, saying, “Unfortunately, there are a number of tests already out there in the market which are not reliable simply because they haven’t been tested sufficiently.”
In reference to the initial release of serological COVID-19 antibody tests, CEO Severin Schwan (above) said during Roche Holding’s first quarter earnings call that, “It’s a disaster. These tests are not worth anything, or have very little use,” reported CNBC. He added, “This is really what matters. Every kind of amateur could produce an antibody test. The two of us could do it overnight in the garage. That’s not the problem. The question is, does it really work? And for that, you have to do testing and validation.” (Photo copyright: Reuters/Arnd Wiegmann.)
A ‘Wild West’ of Unregulated Assays
Prior to issuing tougher rules for how a manufacturer can market a COVID-19 serological test, the FDA had listed about 200 serological tests designed to identify antibodies produced by the human immune system in response to a SARS-CoV-2 infection. This is the process of seroconversion, which is the development of detectable antibodies in a patient’s blood against a pathogen. Detection of IgG antibodies indicates exposure to SARS-CoV-2, according to ARUP Laboratories.
Public health experts have raised questions about the proliferation of such tests for the new coronavirus. Under the FDA’s previous March 16 rules—which were more relaxed than those FDA applied when granting EUAs—the agency was swamped with requests to review more than 200 COVID-19 antibody tests. The looser regulations resulted in nearly no oversight of those tests, reported the Associated Press (AP).
In comments to the AP, Eric Blank, DrPH, Senior Director of Public Health Systems and Programs for the Association for Public Health Laboratories (APHL), said, “Right now it’s a wild west show out there. It really has created a mess that’s going to take a while to clean up.”
“In the meantime,” Blank added, “you’ve got a lot of companies marketing a lot of stuff and nobody has any idea of how good it is.” Blank confirmed to Dark Daily that he made these comments and stands by them.
Calls for Closer Scrutiny of Serological Antibody Tests
In response to the FDA’s March 16 rules for COVID-19 serology tests, APHL requested the federal agency to review its looser approach to reviewing these tests. The impact of the FDA’s much tougher COVID-19 serological testing rules released on May 4 was immediate.
In a press release issued on May 2, the FDA said, “to date, the FDA has authorized 105 tests under EUAs, which include 92 molecular tests, 12 antibody tests, and one antigen test.”
Clinical laboratories in the United States still face difficult challenges if they plan to launch their own COVID-19 serology testing programs. They must select one or more tests from among the antibody and antigen tests that have an FDA EUA. However, data for each of these tests is not as comprehensive as is the data for diagnostic test kits reviewed by the FDA and cleared for market under the pre-market approval process.

Westgard, PhD, and Sten Westgard of Westgard QC, Inc., and the full program is available for free download by clicking here, or by placing this URL in your web browser: https://www.darkdaily.com/webinar/quality-issues-your-clinical-laboratory-should-know-before-you-buy-or-select-covid-19-serology-tests/.
In the webinar recording, the Westgards provide a detailed overview of what elements are required for a clinical lab to have confidence that its COVID-19 serology testing program is producing accurate, reliable results. They explain that labs must understand the unique aspects of the populations they are testing in their communities. All of these factors can then be used by labs to evaluate the different COVID-19 serology tests available for them to purchase, and to select the test that best fits their lab’s capabilities and the characteristics of the patient population that will be tested.
Another important requirement for clinical laboratories to understand is the list of steps necessary to bring up a COVID-19 serological testing program. That starts with validating the test, then bringing it into daily production. As that happens, issues associated with quality control (QC), proficiency testing (PT), and regulatory compliance take center stage, so that the clinical lab has high confidence in the accuracy and reproducibility of the COVID-19 serology test results they are using in patient care or in support of employers who are screening employees for COVID-19.

As federal and state officials ease many regulatory requirements to speed new COVID-19 serology tests to market with minimum data about performance, labs are left with important questions to answer on their own
Every day, elected officials at all levels of government call for a huge expansion of COVID-19 serology testing. But, as most clinical laboratory managers and pathologists know, it is a complex undertaking for a lab to select any serological test, validate it, then run it daily in support of patient care, and have confidence that the results are accurate and reproducible.
Clinical laboratories across the United States understand the volume of testing will be in the tens of millions—even hundreds of millions—of COVID-19 serology tests. That is an important financial opportunity because it gives clinical labs the opportunity to generate some cash flow to offset the 60% decline in daily routine specimens they have experienced since most states enacted shelter-in-place orders in early March.
But this big opportunity to serve physicians and patients with COVID-19 serology testing also comes with equally big risks. There are three major risks a COVID-19 serology testing program that clinical labs must successfully address, otherwise the consequences can be devastating.
Three Major Serology Testing Risks for Clinical Laboratories
Risk one comes during the time when medical laboratories shop for COVID-19 serology tests. As of this writing, about 20 such tests have an emergency use authorization (EUA) with the Food and Drug Administration (FDA) and more are expected to obtain an EUA. As is true with everything in life, not all of these tests will perform equally. The risk to the lab is that it purchases a COVID-19 assay that later proves to be unreliable, despite the lab’s rigorous validation process.
Risk two derives from the fact that new diagnostic methods are being incorporated into the serology tests that companies are submitting to the FDA for an EUA. Although the data submitted to the FDA may indicate acceptable performance to the federal agency, in actual clinical use many unexpected or unknown factors could be recognized which lower confidence that the new method utilized by this particular assay is producing accurate results. That risk would only be recognized downstream from validation and the lab would find itself dealing with unhappy physicians, patients, and employers (who were using the test to check the health of their employees).
Risk three is supply chain risk. Will the manufacturer of the COVID-19 serology test be capable of supplying all of its clinical lab customers with adequate supplies to meet each lab’s demand for this testing? New manufacturers have an unknown track record in their ability to supply their lab customers. But even the largest in vitro diagnostics (IVD) manufacturers may need to ration kits, reagents, and other consumables to the large number of medical laboratories they serve. This happened with the rapid molecular tests for COVID-19. Community laboratories capable of performing these tests could not obtain adequate supplies to serve their client physicians.
Millions Lost on Faulty COVID-19 Serology Test Kits
If there is a fourth major risk to clinical labs performing COVID-19 serology tests for physicians, patients, and employers (who are screening employees in their workplace) it is the negative publicity that can result if a lab’s choice of a COVID-19 serology test ends up generating inaccurate or unreliable test results.
The most recent example is here in the United States. On March 27, Abbott Laboratories announced that the FDA had issued an EUA for its Abbott ID NOW platform and its point-of-care rapid molecular test for COVID-19 that could produce results in less than 15 minutes. This made national news and was hailed regularly during the daily White House COVID-19 Task Force briefings.
What is important with the examples of Spain, United Kingdom, and a major IVD manufacturer is that news outlets are ready to pounce on any evidence that COVID-19 tests are returning inaccurate or unreliable results. This is a source of risk which every clinical laboratory wants to avoid.
How Clinical Laboratories Can Minimize Risk When Buying COVID-19 Serology Tests
During their upcoming webinar, James Westgard, PhD (above), and Sten Westgard of Westgard QC will address how clinical laboratory leaders can evaluate different serology COVID-19 tests by: understanding the testing architecture and intended medical use of COVID-19 testing, taking inventory of lab resources; navigating EUA, LDT, and non-EUA regulatory approval; assessing the expected performance of test methods; understanding the critical performance characteristics for COVID-19 testing; and much more. (Photo copyright: Dark Daily.)
This is an exceptional opportunity to gain an inside perspective of how your lab can address the three major risks identified above when selecting a COVID-19 serology test for use in patient care. You’ll gain essential insights about how to assess the public data on tests with an EUA.
This webinar presentation will also discuss how your lab should view all of its COVID-19 testing as a single program. That’s because your lab may test the same patient with a rapid molecular test, then later do serology tests in the days after the patient may have cleared the infection.
