The University of Texas (UT) Southwestern researchers have created a rapid Covid-19 test that can identify different variants of the coronavirus in as little as four hours.
The researchers hope doctors can use their test, called CoVarScan, to tailor Covid-19 treatments to patients based on which variant the patients have.
