Coronavirus tests performed in labs are the gold standard for accuracy, and antigen tests are a fast and inexpensive alternative. But backers of a third type of test, developed by a Nobel Prize winner using cutting-edge CRISPR technology, say it has the potential to be all three: rapid, accurate and inexpensive. Dr. Jennifer Doudna, a University of California, Berkeley researcher whose pioneering work in CRISPR earned a share of this year's Nobel Prize in chemistry, said the test can be done quickly and doesn't require a lab.  "We have a ways to go before CRISPR-based diagnostics reach widespread use, but I believe we'll see an impact during the current pandemic," Doudna said. "Because it is simple to adjust these tests to detect other targets, the platform we're developing now is laying the groundwork to deploy CRISPR for rapid diagnosis during future outbreaks."
