FDA approved the first test that detects coronavirus by analyzing respiration. The test should be performed by a trained operator, but the test takes only about three minutes.
The test detects respiratory chemicals associated with the pathogen. If the test is positive, the agency recommends PCR diagnostics. According to the FDA, the approval of the breath test is another example of the rapid innovation that is emerging with the COVID-19 tests.
To perform the test, you need equipment the size of hand luggage. We should note that other tests for COVID-19 require a nasal swab or saliva sample. The most accurate way to detect the virus is PCR testing.
