US Universities Roll Out COVID Spit Tests

VOA Student Union

   A recently approved rapid saliva test for COVID-19 is already being

   Also called spit tests, they produce results in less than 24 hours,
   cost about $10, and are less invasive than the standard swab that is
   placed deep into the nose.
