What type of swab is used for the pooled test?

This is a self-collected anterior nasal (AN) swab. Unlike a nasopharyngeal swab, which reaches deep into the nose to take a sample from the back of the throat, an AN sample is taken from the lower part of the front of the nose , at least half an inch inside the nostril. This method both increases comfort and requires less PPE than nasopharyngeal swabs. Instead of a healthcare provider performing the test, students can easily collect their own samples under teacher supervision.
