I just made a project, added all my exams (they were piling up, me and my psychiatrist had been investigating for a year this to no avail) and started talking to it about my symptoms.

Within a few iterations of this it gave me a simple blood panel, then I did that one and it kept suggesting more simple lab or at home tests and we kept going through them until I was reasonably certain of “something” and now that I have hypothesis I am going to a doctor. I think it’s done a great job. I also kept asking it for simple lifestyle interventions to prevent progression of my issue and it consistent nailed it - one particular interverntion (adding salt to water and drinking it to prevent symptoms) made a huge improvement to my life - I was barely working before that.

I added in some text the instructions box (project master prompt) for it to realise - it’s not medical advice and I am aware of that (prevents excessive guardrails) - add confidence intervals and probability to all diagnostic statements (prevents me + Claude going into rabbit holes so easily, it often has 70-80% certainty of what it’s saying, but it’s clear that it doesn’t use the right language) - that It was talking to an non expert, to use simple language but to go into detail when necessary. I also ask it to stop doing unnecessary constant follow up questions to every answer as that causes me anxiety. I can share the prompt, in fact I might do so later as it might be useful to others.
