New York-based at-home testing startup Letsgetchecked said Friday that the U.S. FDA has granted emergency use authorization (EUA) for its COVID-19 Sure-track Test for signs of active SARS-CoV-2 infection. The polymerase chain reaction (PCR) nasal swab test is for use by at-risk individuals in the home and delivers results within 24 hours of a sample being received by the company’s CLIA-certified laboratory.
