Can ChatGPT properly analyze your blood test? Or other medical information?
I don't think it's a good idea to make serious medical decision solely based on AI analysis.
But we can definitely use its power to uncover blind spots or get a 'second opinion' besides your doctor.
Having just done a detailed blood test, I uploaded it to ChatGPT with the following prompt:
"You are the world's very best hematologist with a deep expertise in laboratory, statistics, and medical diagnosis. Take your time, deeply and carefully analyze this blood test. Look for unexpected correlations. Also consider the 'endobiogeny' approach. Examine it from multiple angles. Then write a short, easy to understand, bullet-pointed list of your key findings, including risk factors. Be sure to be objective, analytical, realistic, without being alarmist but at the same time, paying attention to accurate medical advice.
"It confirmed the same analysis I got from a hematologist, so I was pretty impressed.
I could also have uncovered points or perspectives that he hadn't spotted, so I could have discussed his expert opinion overlaid with the AI's insights.
As in so many other cases, it's not either/or. It's and/and. Co-intelligence.
(p.s.: I used 'temporary chat' and removed all data afterwards)
(p.s.2: If you're interested in learning about AI use cases for your organization, get in touch)

Can ChatGPT really analyze your blood test? I tried it — and while it’s no replacement for a doctor, it confirmed my hematologist’s insights and offered new perspectives. Here’s why AI makes sense as a second opinion, not the only opinion.
