OROPHARYNGEAL SECRETIONS

About:

• False negatives have been reported several times during the Covid-19 pandemic. These results have come up during nasal swab testing of patients who have seemingly recovered from the disease — but have later been found to be still carrying the virus.
  
  
• Now, researchers have reported that testing of oropharyngeal secretions — secretions from the part of the throat at the back of the mouth — may reduce the number of false negative results. They have published their findings in the Journal of Dental Research.
