The first COVID-19 test using saliva samples that patients collect at home has been approved by the U.S. Food and Drug Administration.
The emergency use authorization was issued to Rutgers Clinical Genomics Laboratory for the diagnostic test using home-collected samples. Patients return their sample to the New Jersey-based lab in a sealed package for analysis.
The screening is the only authorized test that uses saliva samples to check for the new coronavirus that causes COVID-19. It is available only with a prescription.
At-home saliva testing has several advantages over traditional nasal testing, in which a health care worker inserts a swab deep into the patient's nose and rotates it to extract a sample.
