The U.S. Food and Drug Administration has granted emergency use authorization for scientists at UCLA Health to begin using a new method of COVID-19 detection using sequencing technology called SwabSeq. The method is capable of testing thousands of samples for coronavirus at the same time, producing accurate, individual results in 12 to 24 hours.

SwabSeq adds a unique molecular bar code to each sample in the first step of its processing. The samples are then combined in a sequencer
