What are the differences between the nasal swab and saliva tests for COVID-19?
See full answerSamples for COVID-19 tests may be collected through a long swab that is inserted into the nose and sometimes down to the throat, or from a saliva sample.The saliva test is easier to perform — spitting into a cup versus submitting to a swab — and more comfortable. Because a person can independently spit into a cup, the saliva test does not require interaction with a healthcare worker. This cuts down on the need for masks, gowns, gloves, and other protective equipment, which has been in short supply.Either saliva or swab samples may be used for PCR tests, which detect genetic material from the coronavirus. Swab samples can also be used for antigen tests, which detect specific proteins on the surface of the coronavirus.
Have saliva tests been approved by FDA as a sample for the coronavirus disease testing?
This is the fifth test that the FDA has authorized that uses saliva as a sample for testing. Testing saliva eliminates the need for nasopharyngeal swabs, which have also been prone to shortages, and alleviates the patient discomfort associated with these swabs. Since the saliva sample is self-collected under the observation of a healthcare professional, it could also potentially lower the risk posed to healthcare workers responsible for sample collection.
