This is actually true. We have an over testing problem in the western world and it does cause some people harm, at least in the form of stress and anxiety caused by believing you have something that you don’t (due to false positives), or in some cases in the form of unnecessary operations and their associated medical risk.

And that’s without getting into the financial impacts, whether that be an impact on an individual or, in a civilised country, on the government.

That’s obviously not to say that nothing should be tested. Only that tests should be limited to cases with a heightened risk, be it someone showing symptoms (as OP obviously was, which is why this general problem of over testing is not applicable in this case) or being part of a demographic know to have heightened risk, as determined by experts and medical best practices.
