Clinical laboratory executives and pathology leaders may want to develop strategies for supporting the growing numbers of at-home screening and diagnostic test users
Findings of a national poll conducted by the University of Michigan (U-M) exploring consumers’ purchases suggests seniors are becoming more comfortable with ordering and using at-home medical testing. Their choice of tests and opinions may be of interest to clinical laboratory executives, pathologists, and primary care physicians considering programs to support self-test purchasers.
The researchers found that 48% of adults, ages 50 to 80, purchased at least one at-home medical test, and that 91% of the buyers indicated intentions to purchase another test in the future, according to a U-M news release.
In their paper, they note that “validity, reliability, and utility of at-home tests is often uncertain.” Further, understanding and responding to test results—especially since caregivers may not have ordered them—could lead to “a range of unintended consequences,” they wrote.
“As a primary care doctor, I would want to know why my patient chose to take an at-home test that I didn’t order for them. We also need to understand in greater detail why folks use at-home tests instead of traditional means, beyond convenience,” said the U-M study’s lead author Joshua Rager, MD, a research scientist at William M. Tierney Center for Health Services Research at Regenstrief Institute, who is now an assistant professor of medicine, Indiana University, in a news release.

Free COVID-19 Tests Ignite At-Home Testing
In their Journal of Health Care paper, the U-M researchers speculate that curiosity in at-home testing may have been propelled by the offer of free COVID-19 tests by the US government starting in 2021 during the pandemic.
They also noted the different ways at-home test kits are performed by healthcare consumers. Some, such as COVID-19 rapid antigen tests, return results to users in a few moments similar to pregnancy tests. Others involve self-collecting specimens, such as a stool sample, then sending the specimen to a clinical laboratory for analysis and results reporting to physicians.
Of those older adults who participated in U-M’s National Poll on Healthy Aging study, the following bought at-home medical tests online or from pharmacies and supermarkets, according to U-M’s paper:
As to perceptions of at-home medical testing by users, when polled on their test experience, the surveyed seniors reported the following:
75.1% perceived at-home medical tests to be more convenient than conventional medical tests.
59.9% believe the tests “can be trusted to give reliable results.”
54.8% believe the tests “are regulated by government.”
66% called them a “good value.”
93.6% indicated results “should be discussed with my doctor.”
Inconsistency in how people shared test results with their healthcare providers was a concern voiced by the researchers.
“While nearly all patients who had bought an at-home cancer screening test shared the results with their primary care provider, only about half of those who tested for an infection other than COVID-19 had. This could have important clinical implications,” the researchers wrote in their paper.
Confusion over Government Regulation
The U-M study also revealed consumer misunderstanding about government regulation of at-home clinical laboratory tests purchased over-the-counter.
The US Food and Drug Administration (FDA) cleared “some diagnostic at-home tests for over-the counter use. But many tests on the market are unregulated or under-regulated,” the authors wrote, adding, “Our results suggest, however, that patients generally believe at-home tests are regulated by government, but a substantial minority did not, which may reflect public confusion in how at-home testing is regulated.”
Women, College-Educated Buy More At-Home Tests
Purchase of at-home tests varies among groups, as follows, the news release noted:
56% and 61% of older adults with a college degree or household income above $100,000, respectively, were “much more likely” to buy at-home tests than people in other income and education brackets.
87% of women would buy at-home tests again compared with 76% of men.
89% of college-educated people would purchase the tests again, compared with 78% of people with high school educations or less.
Future U-M research may explore consumers’ awareness/understanding concerning federal regulations of at-home testing, Rager noted.
“At-home tests could be used to address disparities in access to care. We hope these findings will inform regulators and policymakers and spark future research on this topic,” he said in the news release.
The U-M Institute for Healthcare Policy and Innovation survey results confirm that the country’s senior generations are becoming comfortable with at-home and self-testing options. As Dark Daily has previously suggested, clinical laboratories may want to develop service offerings and a strategy for supporting patients who want to perform their own lab tests at home.
Abbott sends the SARS-CoV-2 test results directly to patients’ smartphones, which can be displayed to gain entrance into areas requiring proof of COVID-19 testing
There is no greater example that COVID-19 is a major force for change in the clinical laboratory industry than the fact that—though the US federal government pays 50% of the nation’s total annual healthcare spend of $3.5 trillion—it recently spent $760 million to purchase 150 million COVID-19 tests from Abbott Laboratories (NYSE:ABT), an American multinational medical devices and healthcare company headquartered in Abbott Park, Ill., “to expand strategic, evidence-based testing in the United States,” according to the company’s website.
In August, the federal Food and Drug Administration (FDA) granted an emergency use authorization (EUA) to Abbott for its BinaxNOW portable rapid-response COVID-19 antigen (Ag) test. The credit-card sized test costs $5 and can return clinical laboratory test results in minutes, rather than hours, days, or in some cases, weeks, the Wall Street Journal (WSJ) reported.
The test includes a free smartphone app called NAVICA, which enables those tested to receive their test results directly on their mobile devices—bypassing the patient’s primary care physicians.
According to Abbott’s website, the app “allows people who test negative to get an encrypted temporary digital NAVICA Pass, similar to an airline boarding pass. NAVICA-enabled organizations will be able to verify an individual’s negative COVID-19 test results by scanning the individual’s digital NAVICA Pass to facilitate entry into facilities.”
This feature of Abbott’s new COVID-19 test is a good example of how quickly innovation in the medical laboratory testing profession is bringing new features and new capabilities to the marketplace. By marrying the SARS-CoV-2 test with the NAVICA Pass feature, Abbott hopes to deliver increased value—not just to physicians and their patients—but also to employers with employee screening programs and federal government programs designed to screen federal employees, as well as being used for screening travelers at airports and other transportation hubs.
Abbott appears to be banking that in the future such identification will be required to “enter organizations and other places where people gather,” as the company’s website states.
Testing Limited to CLIA-Certified Clinical Laboratories
An HHS news release announcing the government’s planned distribution of the BinaxNOW tests stated that “Testing will be potentially deployed to schools and to assist with serving other special needs populations.”
In the news release, Alex Azar, HHS Secretary, said, “By strategically distributing 150 million of these tests to where they’re needed most, we can track the virus like never before and protect millions of Americans at risk in especially vulnerable situations.”
The EUA adds that “Testing of nasal swab specimens using [BinaxNOW] … is limited to laboratories certified under CLIA that meet the requirements to perform high, moderate, or waived complexity tests. This test is authorized for use at the [point of care], i.e., in patient care settings operating under a CLIA Certificate of Waiver, Certificate of Compliance, or Certificate of Accreditation.”
The FDA’s EUA describes the BinaxNOW portable rapid-response COVID-19 antigen test (above) as “a lateral flow immunoassay intended for the qualitative detection of nucleocapsid protein antigen from SARS-CoV-2 in direct nasal swabs from individuals suspected of COVID-19 by their healthcare provider within the first seven days of symptom onset.” The test costs $5 and Abbott sends results directly to the patient’s smartphone using the free NAVICA app included with the test.

IVD Companies See Boom in COVID-19 Test Sales
Demand for COVID-19 testing has created opportunities for in vitro diagnostics (IVD) companies that can develop and bring tests to market quickly.
Recent issues of Dark Daily’s sister print publication—The Dark Report (TDR)—covered IVD companies’ second quarter (Q2) boom in sales of COVID-19 instruments and tests, while also noting a fall-off in routine clinical laboratory testing during the COVID-19 pandemic.
Abbott Laboratories saw molecular diagnostics sales increase 241% in Q2 driven by $283 million in sales of COVID-19 testing, while rapid diagnostic COVID-19 testing rose 11% on $180 million in sales in Q2, TDR reported, based on Abbott data.
“There is huge economic incentive for diagnostic companies to develop technologies that can be used to create rapid tests that are cheap to perform,” said Robert Michel, Publisher and Editor-in-Chief of TDR and Dark Daily. “In this sense, COVID is a major force for change.”
“This new COVID-19 antigen test is an important addition to available tests because the results can be read in minutes, right off the testing card,” said Jeff Shuren, MD, JD (above), Director of the FDA’s Center for Devices and Radiological Health (CDRH), in an FDA news release announcing the federal government’s $760 million purchase of 150 million Abbott BinaxNOW rapid-response antigen COVID-19 tests. “This means people will know if they have the virus in almost real-time. Due to its simpler design and the large number of tests the company anticipates making in the coming months, this new antigen test is an important advancement in our fight against the pandemic.” (Photo copyright: The New York Times.)
Thus, Abbott is determined to ensure this product launch is successful and that the test works as promised. According to a news release, “In data submitted to the FDA from a clinical study conducted by Abbott with several leading US research universities, the BinaxNOW COVID-19 Ag Card demonstrated sensitivity of 97.1% (positive percent agreement) and specificity of 98.5% (negative percent agreement) in patients suspected of COVID-19 by their healthcare provider within the first seven days of symptom onset.”
“The massive scale of this test and app will allow tens of millions of people to have access to rapid and reliable testing,” said Joseph Petrosino, PhD, professor and chairman, Molecular Virology and Microbiology, Baylor College of Medicine, in the Abbott news release. “With lab-based tests, you get excellent sensitivity but might have to wait days or longer to get the results. With a rapid antigen test, you get a result right away, getting infectious people off the streets and into quarantine so they don’t spread the virus.”
Abbott has invested hundreds of millions of dollars in two manufacturing facilities where the tests will be made, John Hackett Jr, PhD, an immunologist and Abbott’s Divisional Vice President Applied Research and Technology, and lead scientist on the BinaxNOW project, told The Atlantic.
“Our nation’s frontline healthcare workers and clinical laboratory personnel have been under siege since the onset of this pandemic,” said Charles Chiu, MD, PhD, professor of Laboratory Medicine at University of California, San Francisco, in the Abbott news release. “The availability of rapid testing for COVID-19 will help support overburdened laboratories, accelerate turnaround times, and greatly expand access to people who need it.”
However, other experts are not so sure. In the Atlantic article, Michael Mina MD, PhD, Assistant Professor Epidemiology at Harvard’s T.H. Chan School of Public Health, voiced the need to test both asymptomatic and pre-symptomatic people. “This is the type of [COVID-19] test we have been waiting for—but may not be the test.”
Nevertheless, the federal government’s investment is significant. Abbott plans to start shipping tens of millions of tests in September and produce 50 million tests per month starting in October, Forbes reported.
Shifting Clinical Laboratory Paradigms
BinaxNOW will be performed without doctors’ orders, in a variety of locations, and results go directly to patients’ smartphone—without a pathologist’s interpretation and medical laboratory report. This is new ground and the impact on non-CLIA labs, and on healthcare in general, is yet to be seen.
Clinical laboratory managers will want to monitor the rise of rapid-response tests that can be easily accessed, conducted, and reported on without physician input.
