Testing accessibility has always been a problem when it comes to fighting the coronavirus. And even as that has improved, a slow turnaround rate has often made test results useless.
That's why some researchers and public health experts are starting to emphasize rapid result coronavirus tests even if they're less accurate than the time-intensive PCR tests, The New York Times reports. Their logic? "Even if you miss somebody on Day 1, If you test them repeatedly, the argument is, you'll catch them the next time around," said Omai Garner, director of clinical microbiology in the UCLA Health System.
The experts who back an emphasis on quicker tests cite the failure of long-term tests to stem coronavirus spread throughout the U.S. "If you had asked me this a couple months ago, I would have said we just need to be doing the PCR tests," said Susan Butler-Wu, a clinical microbiologist at the University of Southern California. But, she added, it's now "kitchen sink time, even if the tests are imperfect."

Still, PCR coronavirus tests rely on laboratory procedures to generate their results, and even quick-result tests require "specialized machines that are neither cheap nor easy to produce in bulk," the Times writes. But antigen tests, which identify a protein in the coronavirus, could be performed at any doctor's office or even at home, and could be mass-produced to cost just a few dollars each. Some companies are focused on developing these low-cost tests and ramping up their production until a vaccine is found.
