Locate a puncture siteit should be slightly off-center (lateral side of) on the fleshy part of the fingertip. There are two main types of viral tests: nucleic acid amplification tests (NAATs) and antigen tests. A: The FDA issued the Enforcement Policy for Viral Transport Media During the Coronavirus Disease 2019 (COVID-19) Public Health Emergencyto help address transport media availability concerns resulting from the COVID-19 public health emergency. In Australia, PCR tests are used to diagnose SARS-CoV-2 infections. These policies apply to swab-based specimen collection by healthcare providers (HCP), and to anterior nares (nasal) and mid-turbinate specimen collection onsite by self-collection.
