A: Based on the available evidence at this time, the FDA believes that the following specimen types are appropriate for swab-based SARS-CoV-2 testing: Although all of the above options are appropriate for clinical testing, nasopharyngeal specimens are generally considered to yield the most sensitive test results and are therefore the preferred choice as a reference (comparator) for clinical investigations and validating new methodology. While rotating the swab by rolling the handle in the fingertips, gently insert the swab less than one inch (about 2 cm) into the nostril. Microfiber provides high surface area for rapid capillary absorption of fluid specimens.
