Ascension Parish What should I expect before visiting a test site? You'll need to wear a mask onsite and stay in your car before getting testing. For those 13 years and older, expect the site to have a self-administered nasal swab test. This allows you to swab your own nose on site while in your vehicle. Once that's done, you'll drop the sealed sample into a container on your way out of the drive-thru site. For children age 12 and younger, parents will administer tests to them.
