This isn't really a fair criticism. I could be wrong, but I believe your comment reflects a bit of naivete about the current state of evidence-based medicine.

To evaluate the value of performing a diagnostic test as an intervention, you DO have to look at final actual patient outcomes at an appropriate end target which includes sending people unnecessarily down different treatment paths, including additional testing with additional risks. And most importantly is that, in fact, mere knowledge of diagnostic results has been PROVEN to cause harm in many scenarios.

Now... if a patient WANTS that test, I think it should be available. But whether or not it should be performed routinely without prompting is an appropriate question for regulatory bodies.
