Thermometers are well understood, simple devices, and there are other complementary checks (e.g. does my forehead feel hot) if they fail.

This project might lead to people thinking they're in the clear and not seek appropriate medical treatment, or be overtreated due to an error. You should always talk to a qualified doctor if you're concerned about your health, and not use projects like these for decision making.

I don't see how a passive scan like this can be harmful . Ofcourse if it does show a positive one should confirm further with a biopsy or other standard confirmation diagnostic. As for false negatives... If you feel something is wrong you should get it checked thoroughly anyway .

[dekhn]

you literally just said the scan has no value. THe point of a scan like this is to have absurdly low false negative and positive rates so that it's actionable. Unactionable medical diagnostics are worthless and just cost (money, fuel, time).

There are more costs, like others have described it might lead to unnecessary biopty that has real risks.

So you should ignore it and see a doctor regardless.

In an ideal world, that would be the case. However, people aren't 100% rational agents motivated by logic.

My aunt was diagnosed with Multiple Sclerosis which led her to lose her eyesight from her left eye, because she refused to get a thorough checkup by a professional, and even today whenever I tell her that I visited the doctor for an issue she has... not very good words to say (something something "you are a chicken, you're hypochodriac etc). And I'm saying this without entertaining the probability of her visiting a professional who just happened to be in a bad day, which could potentialy lead to a wrong diagnosis.

I've been hunting down my own diagnosis for symptoms everyone seems to tell me that aren't serious (nail discoloration and a 24/7 headache that feels like my arteries are pulsing, which lasts for YEARS, cold fingertips during the winter, and more).

I get what you're trying to say and I agree with the general message. However, more checkpoints to catch a potential failure are good. For example, if someone were to make a take-at-home device which scans nailfold capillaries (no reason for something like that to exist) I'd get that in a heartbeat. I'm being actively ignored by every medical professional that I have visited, and if I'm not ignored they give the minimum amount of attention, kind of like "well, it's not like you're dying so who cares?"

Fair note: I'm from Europe.

If you don't feel good yes you should see a doctor regardless. Let's say you get a scan every year . If the scan is able to detect something earlier than a radiologist is able to identify i think it's worth paying attention to.
