COVID-19 Breathalyzer Test Receives FDA Approval
Sending a swab up the nose to swirl about and test for COVID-19 has become a familiar but unsettling feature of living through the epidemic, whether it's a PCR test or an at-home version. But what if there was another option? For the first time, health officials in the United States have approved the COVID-19 breathalyzer, a device that promises results in under three minutes. As new sub-variants drive up case numbers, some experts anticipate that this will be the first of many new techniques to identify the virus and, as a result, improve how we live with it. There's even a chance that breath testing could one day be used to detect and monitor other diseases like cancer. So, how far has technology progressed? And, more importantly, could it truly replace the nasal swabs we've come to despise?
