Researchers received U.S. government clearance for the first saliva test to help diagnose COVID-19, a new approach that could help expand testing options and reduce risks of infection for health care workers.
With the new saliva-based test, patients are given a plastic tube into which they spit several times. They then hand the tube back to the health care worker for laboratory processing.
An infectious disease expert not involved with the new test said it would help overcome some of the patient discomfort and difficulties in taking swab samples. Rutgers tested the accuracy of its method by taking both saliva and swab samples from 60 patients. The results from patients’ saliva samples had a 100% match with results from the swabs.
