my sister is going to a clinic that gives her literally water+salt in a little cup, she puts it in her mouth and then spits it back and they test the cup

no weird testing pole

i do not trust the pole either because those weird companies can put anything they want in it and i dont trust them

My brother does also saliva test in another clinic , they do use pole but they get saliva from near your tongue from mouth, no sticking sh1t in the nose etc
gpt
they can do cheaper rapid in pharmacy (6-7-8 euro) but they prefer to give 10 euro in clinic for this kind of test
