Look at the supplements world, where grifters are shilling chemicals that cause harm and make radical claims for absurd markups. Or gas station pills. You want those companies making Alzheimer's tests? People going in to a 7-11 and buying a "all illness test card" that tells people they do or don't have degenerative diseases?
No, it's very very important to ensure tests are actually indicative and ensure they are well made. To do that, a regulating body needs to be involved.
Imagine if every new AI model had to be "cleared" by a government regulator. The role of government in healthcare evaluation needs to be simplified and streamlined. The liability needs to be shifted to doctor, and if it's a case of charlatanism, that liability should include a lengthy prison sentence.
But only another medical professional would know that; the patients were completely oblivious. I said she should blow the whistle but she “didn’t want to rock the boat”. It definitely changed how I feel about doctors. There’s a massive level of trust there, which most doctors will honor but a few will exploit.
This is like saying AI developers should be qualified to evaluate the effacy of a model without testing the model.
Seems much better use of time and money to have people developing tests meet a pre-defined standard and after that point they're allowed to flood doctors with marketing for the tests.
What use is future medical advancements if it can't meet low bars like proving it works?
There is potential harm from the procedure itself because of https://en.wikipedia.org/wiki/Opportunity_cost and https://en.wikipedia.org/wiki/Budget_constraint and because sticking needles in people and drawing blood carries inherent medical risks.
