Isolation means you stay home and away from others (including household members) for the recommended period of time to avoid spreading illness. However, certain policies regarding the distribution and offering of certain tests for clinical use prior to or without an EUA remain in the current version of the Policy for Coronavirus Disease-2019 Tests. Such laboratories may perform tests for which they meet the qualifications of the authorized settings included in the EUA. In cases of discordant test results from different types of tests, results from laboratory-based NAATs should be prioritized over any POC or self-administered test.

Several EUAs have been issued for tests that must be performed in a laboratory, but for which the samples can be collected at home and sent to the laboratory. The FDA will likely authorize additional NAAT methods in the future. Screening testing for COVID-19 looks for infections in individual people even if there is no reason to suspect the specific person has an infection or known COVID-19 exposure. They help us to know which pages are the most and least popular and see how visitors move around the site. Ct values are not comparable between tests and may not be comparable between different lots of the same test, as they are dependent on various factors such as the specimen collection, storage, transport, time from collection, nucleic acid target, primers and probes, extraction method, amplification method, instruments used, etc. All information these cookies collect is aggregated and therefore anonymous.

In this context, "confirmation" does not require documentation of the type of test performed; the provider's documentation that the individual has COVID-19 is sufficient. What does it mean if the specimen tests negative for 2019-nCoV? Some examples of screening testing include testing by a workplace or school of all employees, students, and/or faculty returning to the workplace or school regardless of exposure or signs and symptoms, with the intent of using those results to determine who may return or what protective measures to take on an individual basis. CDC has updated select ways to operate healthcare systems effectively in response to COVID-19 vaccination. zkS|"n5U&?G The level of sensitivity for the detection of SARS-CoV-2 genetic material in a specimen also varies depending on the methods and application of the NAAT.
