There's a new COVID-19 test from healthcare technology maker Abbott that looks to be the fastest yet in terms of producing results, and that can do so on the spot right at point-of-care, without requiring a round trip to a lab. This test for the novel coronavirus causing the current global pandemic has received emergency clearance for use by the U.S. Food and Drug Administration, and will begin production next week, with output of 50,000 per day possible starting next week.
The new Abbott ID NOW COVID-19 test uses the Abbott ID NOW diagnostics platform, which is essentially a lab-in-a-box that is roughly the size of a small kitchen appliance. Its size and that it can produce either a positive result in just five minutes or a negative one in under 15 mean that it could be a very useful means to extend coronavirus testing beyond its current availability to more places including clinics and doctor's offices, and cut down on wait times both in terms of getting tested and receiving a diagnosis.
Unlike the rapid tests that have been used in other countries, and that received a new type of authorization under an FDA guideline that doesn't confirm the accuracy of the results, this rapid testing solution uses the molecular testing method, which works with saliva and mucus samples swabbed from a patient. This means that it works by identifying a portion of the virus's RNA in a patient, which means it's much better at detecting the actual presence of the virus during infection, whereas other tests that search the blood for antibodies that are used in point-of-care settings can only detect antibodies, which might be present in recovered patients who don't actively have the virus.
The good news for availability of this test is that ID NOW, the hardware from Abbott that it runs on, already "holds the largest molecular point-of-care footprint in the U.S.," and is "widely available" across doctor's offices, urgent care clinics, emergency rooms and other medical facilities.
In total, Abbott now says that it believes it will produce 5 million tests in April, split between these new rapid tests and the lab tests that it received emergency use authorization for by the FDA on March 18.
Testing has been one of the early problems faced by the U.S. in terms of getting a handle on the coronavirus pandemic: The country has lagged behind other nations globally in terms of per capita tests conducted, which experts say has hampered its ability to properly track and trace the spread of the virus and its resulting respiratory disease. Patients have reported having to go to extreme lengths to receive a test, and endure long waits for results, even in cases where exposure was likely and their symptoms match the COVID-19 profile.
