RE:RE:RE:RE:RE:NEWS...but not news...In March 2021, FDA Guidance was provided to test developers who were seeking emergency use authorization (EUA) of certain tests that could be used for serial testing, which includes the AcuVid™ COVID-19 Rapid Antigen Saliva Test. Serial testing involves testing the same individual multiple times within a few days, and can increase chances of detecting asymptomatic infection that might not always show up with a single test. CDC recommends serial testing at least once per week, along with other mitigation measures, such as masking and social distancing, to reduce disease transmission.
