Let's face it, your personal doctor doesn't have time. He has seven minutes for you, five of which he spends typing on a computer that's still running Windows XP, and the other two minutes pretending to be interested in why your lower back hurts. What if you had a doctor who had all the time in the world, had read all the medical literature since Hippocrates, and didn't play golf on Wednesdays? Today, we're going to turn ChatGPT or Gemini into your personal medical advisor - Doctor ChatGPT.
These are the tools that allow you to give artificial intelligence a “brain” and a “memory.” Today, I’m going to teach you how to digitize your body, upload your blood tests, and create a machine that knows your health better than you do. And don’t worry, you don’t need a PhD in computer science. Just a smartphone and a little common sense. But be careful! This is not a doctor, this is your personal health advisor, included in your ChatGPT subscription. It does not replace a doctor, but it will help you analyze test results that you do not understand.
Phase 1: Digitization or “How to put blood in PDF”
Before we can do the magic, we need data. Artificial intelligence is like an internal combustion engine – give it bad fuel and it will cough. Give it top-notch gasoline and it will fly. Your intelligence, sitting in the drawer under your socks, is that fuel.
Your task is simple but crucial:
-
Scanning: You don't need a scanner the size of a photocopier. Use an app on your smartphone. Scan documents to PDF format. Don't take a picture of them like a beach selfie. They need to be legible.
-
File naming: This is the part where most people get stuck. File name
IMG_4455.jpgIt doesn't tell the artificial intelligence anything. You must name the files chronologically and content-wise.-
Example:
2023-05-12_Krvna_Slika_Laboratorij.pdf -
Example:
2024-01-20_MR_Knee_Examination.pdf -
Example:
2024-03-10_Discharge_Letter_Hospital.pdf
-
Why the date at the beginning? Because that's how your AI doctor will understand timelineHe will understand that cholesterol was high in 2020, but fell in 2024, after that cabbage diet. This is key to analyzing trends.
Important warning: Before you upload anything to the cloud, take a black marker (digital or real) and cover your EMŠO and address. You can leave your name, but out of paranoia – and because Google and OpenAI are not your friends, but corporations – let’s be careful. So… personal data is important, handle it with care. If you’re really concerned about the possibility of misuse, then don’t use it. You do everything entirely at your own risk.
Phase 2: Choosing a weapon – ChatGPT or Gemini?
Both tools are great, but they have their own specifics.
-
ChatGPT (Plus version): It allows you to make “Custom GPT”. This is a mini application within the chat where you can upload up to 20 files to the Knowledge base. You can consolidate blood test results into one file, which you can then replace with an updated one each time.
-
Google Gemini (Advanced): It has a huge “contextual window.” This means you can “throw” hundreds of pages of documents at once and it will chew through them like they’re chips.
For this guide, we will use logic that works on both. If you have ChatGPT Plus, go to “Explore GPTs” -> “Create”. If you have Gemini, simply create a new “Gem”.
Phase 3: “Prompt” – The command that turns the robot into a doctor
This is where the amateurs and the professionals are separated. If you type “Look at my results,” you’ll get a generic answer. We want an analysis worthy of Dr. House (without the cynicism and Vicodin).
Paste the following text into the Instructions field. This is your Golden Prompt:
System command for AI Health Assistant:
Role: You work as an experienced internal medicine specialist and diagnostician with over 20 years of experience. Your approach is analytical, precise, yet empathetic. Your goal is not to diagnose (because you are AI), but to empower the patient by interpreting data, looking for trends, and preparing questions for their treating physician.
Context: The user will upload a series of medical reports (PDF, images). These documents are named in the format YYYY-MM-DD for easier chronological understanding.
Your task:
-
Data analysis: Please review all attached documents.
-
Timeline: Create a chronological overview of key parameters (e.g., movement of cholesterol, sugar, leukocytes over the years).
-
Anomaly detection: Highlight any values that deviate from the reference range. If the value is only slightly elevated, mention this, but put it in context (e.g., “a slightly elevated CRP may only indicate minor inflammation”).
-
Correlation: Connect the dots. Does the drop in iron match the user's description of fatigue in 2023?
-
Language: Communicate in Slovenian, explaining technical terms in brackets in a simple way (e.g. “Hyperlipidemia (elevated blood fats)”).
Output format:
-
Status summary: A brief description of the health profile (2-3 sentences).
-
Trend table: Table with columns [Date, Parameter, Value, Reference value, Comment].
-
Warnings: Red flags that require attention.
-
Questions for the doctor: A list of 3-5 smart, professional questions that a patient should ask their real doctor at their next visit.
Limitation of liability: You must begin or end each answer with a clear disclaimer: “I am an artificial intelligence, not a doctor. This information is for informational purposes only and is not a substitute for professional medical advice.”
Of course, you can also set it differently. More personally, like your personal doctor, who is an excellent internist – Dr. House, Dr. Gruber, Dr. Hauser in one person. And remove most of the filters. Write to him to analyze new conditions and come up with solutions based on historical documents. But be careful! At your own risk. For a “real prompt” you can write me a private message, or subscribe to the newsletter on my website janmacarol.com ….
Phase 4: Driving
Now that you have your “bot”, simply upload to it all those PDFs you created in the first phase.
Tell him: “Analyze my blood counts from 2019 to 2024. Make a chart of liver enzymes and cholesterol trends. Are there any worrying trends?”
The result will shock you. The AI won't just read the numbers; it will notice patterns. It might say: “I’ve noticed that your vitamin D levels drop drastically every year in November, which coincides with your complaints of fatigue. It might be a good idea to check your supplementation in the winter.”
This is something your doctor may miss because they are only looking at the latest report, not the full picture of the last five years.
Conclusion: Is this the future or madness?
Is it dangerous? Maybe if you're an idiot and think it will ChatGPT operated on your appendix. But if you use this as a tool for “second opinion” and for sorting out our own bureaucratic mess, it's the best thing since the invention of penicillin.
It costs you $20 a month (AI subscription), which is less than you'll pay for parking in front of the University College Ljubljana. But you get an analyst who doesn't sleep, doesn't drink coffee, and has read every study in the world.
This tool will not replace your doctor. But you will become that annoying patient, which comes in office ready, with tables and questions that will finally make the doctor have to make an effort. And that, my dears, is progress.
Serious Warning: The “Don’t Be a Fool” Clause
Before you embark on the digitalization of your body, we need to pull the handbrake and pour ourselves some pure wine. What you will create, not a doctor. This is a very advanced statistical model that can perfectly imitate human conversation. It has all the knowledge – but it is not always right and makes mistakes. Just like your personal doctor but statistically less often – which is sad in a way. (read more)
Artificial intelligence “hallucinates.” This is the technical term for when an AI makes a statement of complete nonsense with complete, 100 percent confidence. It can invent a disease that doesn’t exist, or it can miss a obvious signs of a heart attackbecause it was Poorly scanned PDF.
So listen carefully: You do all this solely at your own risk.
If you have chest tightness, difficulty breathing, or bleeding, for God's sake, do not open ChatGPT. Call 112. The use of this tool is intended for prevention, organization, and easier understanding of medical Latin, and in no way for diagnosis or treatment. Don't be the type of person who drives their car into a river because the navigation system told them to. Use this technology as a tool, not as a god. Smart in your hands.
