&gt; Aside from whether their technology actually works or not, the central premise that cheaper, easier and more frequent testing will improve outcomes is unproven. There are many potential downsides.<p>This is an excellent point.  Nevertheless, it&#x27;s very hard to convince patients, and the public, that more tests do not lead to better outcomes.  Think on every time there are revisions to the recommended screening criteria for breast or prostate cancer---it&#x27;s good evidence-based medicine, but there&#x27;s an outcry from the public every time.<p>In addition to your considerations of more testing being invasive and expensive, I&#x27;d also add that overtesting can lead to interventions that present a non-minimal risk to the patient and ultimately increase M&amp;M.
