LabCorp’s at-home COVID-19 test, which is called ‘Pixel,’ has received the first Emergency Use Authorization (EUA) for such a test issued by the U.S. Food and Drug Administration (FDA). The test is an at-home collection kit, which provides sample collection materials including a nasal swab to the user, who then uses the included shipping package to return the sample to a lab for testing.
Until now, the FDA has not authorized any at-home testing or sample collection kits for use, and in fact clarified its guidelines to specifically note that their use was not authorized under its guidelines when a number of startup companies debuted similar products for at-home collection and round-trip testing with labs already certified to run molecular RT-PCR tests to detect the presence of COVID-19.
The FDA notes that only LabCorp’s COVID-19 RT-PCR test has received this authorization, and that it still requires any such test to have an EUA before they can being offering services, whether or not the test is administered at home with the help of guidance from an authorized medical professional via telemedicine. Some labs facilitating at home serology tests using an exception in the FDA guidelines, but these are not viewed by the agency as tests that can confirm a case of COVID-19.
Opening up at-home testing (even via just sample collection, vs. full at-home test administration) is a big step in terms of a change in the way the agency has operated thus far. The FDA has recently updated its guidelines to note that it is working with at-home test providers to determine the best way to make those available to the public, since it “sees the public health value in expanding the availability of COVID-19 testing through safe and accurate tests that may include home collection.”
LabCorp is a U.S. medical diagnostics company with over 40 years of experience, including at-home testing via its Pixel line for colorectal cancer, diabetes, and cardiac lipid conditions. It seems like the FDA is favoring long-standing industry experience in terms of who it’s willing to open up authorizations for with at-home collection, which is likely due to the potential for increased error when you add unsupervised self-collection, packing and logistics into the mix.
Testing for COVID-19 in the U.S. currently relies on drive-through sites, as well as in-clinic and hospital testing. These tests have a high bar for access in terms of risk profile and symptom presentation, and their administration also exposes the healthcare professionals running them to risk of contracting the infection themselves. At-home testing could increase overall testing rates, while decreasing risk to frontline healthcare workers, providing a better picture of the true extent and depth of the COVID-19 pandemic.
