This is exactly why it's a bad idea. I agree that if this technology comes to fruition, it should be in every clinical and research setting as a tool for us to further our understanding.

It shouldn't be a commodified test anyone can do at any time they feel like it. There are so many examples this leading to over or misdiagnosing already. I've seen patients who thought they had diabetes because they got a CGM over the counter and it showed a blood sugar spike during exercise (as in, their body doing exactly what it was supposed to do). He also now avoids oatmeal because "it spikes my blood sugar". Surprise: reddit and tiktok are awash with such stories as well.

I've seen a patient who on a whim decided to get 24hr blood pressure monitoring done, and thought they have severe hypertension because their systolic reached 170 when they were climbing stairs and during a football match because they were cheering and shouting.

In a similar vein, there are shady practicians who offer full body MRI scans, and fMRI brain scans to the well-to-do as a way of diagnosing things, when in fact neither are specific enough to actually diagnose something on their own.

23andme tests sending patients into clinics because they found a specific SNP that may be associated with worse outcomes for a disease.

We have neither the resources nor a specific enough technology (scan shows something: not specific enough to tell us what it is, but it sure is something) to unleash these for the general population to use.
