False positives. My wife underwent multiple tests including a nuclear one to learn that her kidneys aren't exactly the normal shape. Completely harmless.

However, you do have something of a point. The normal screening tests should be able to be ordered by an insurance company or by the patient themselves. If you don't have any other medical issues that need a doctor there's no reason for a visit unless the tests find an abnormality.
