Answer

Where does the sample for antigen come from: from the nasopharynx or is it blood?
As for PCR, the requirement not to drink, eat or brush your teeth is for the accuracy of the analysis. When you eat, drink, or otherwise wash away virus RNA particles from the mucous membranes of the nose and mouth, the material may not be enough to detect traces of the virus.
So focus on the purpose for which you are doing the test. If the goal is to get an accurate result, follow the rules, do not smoke or drink. If the goal is to get a negative result, smoking, eating and other prohibition will only help.

If you rent for traveling abroad, you can eat and smoke. ))) My husband both ate and smoked before passing the express antigen test, the result is negative.
