Now, I live in DK, and my visit to the GP would always go with my hard attempts to convince my GP that something is really wrong and I am not a crazy lunatic who is simply looking for attention. Although, I have never directly asked for a checkup(while being healthy) to look for disease vectors. I’ll ask and see what they say.
I’d prefer if this is outside of the general healthcare system though. I don’t want to occupy Doctors, and medical labs from people who are actually sick _now_ and need those tests, and attention.
