Where are buccal swabs taken from?
cheek
Buccal Swabs are cotton-tipped applicators (similar to a Q-Tip) that are used to collect cheek cells from the inside of a person’s mouth. The cheek cells are used for DNA testing (also referred to as DNA profiling and DNA fingerprinting). Buccal Swabbing is a non-invasive procedure that takes a few minutes.

Should buccal swabs be refrigerated?
How do you store buccal?
Store buccal swabs in the original pouch. Do not use plastic tubes. Bacterial growth in sealed plastic tubes can cause DNA degradation. For best results, ship buccal swab samples at 25°C or below.

But those are slightly different from the lining of the nose and nasopharynx. Throat swabs and saliva tests (taken either by spitting in a cup or swabbing the inside of the mouth) gather the virus more from squamous epithelial cells, whereas nasal swabs grab it more from respiratory epithelial cells.
