As of 13 August 2026, AI can only partly explain your blood test results.

What to actually do

1. Hand it to a person

   The route this page recommends

   Someone with a licence or accountable authority has to sign this before it counts.

2. Use a tool built for this

   Second choice

3. Do it yourself

   The distant third

   A chat interface gets you a draft, but you cannot verify it yourself. That is the catch.

   How to actually do it

   1. Open the original laboratory report or NHS app entry and copy the complete test names, results, units, flags and reference ranges.
   2. Remove your name, date of birth, NHS number, address and other identifying details, while keeping the test values and laboratory ranges unchanged.
   3. Write down the reason for the test, your relevant symptoms and their timing, current medicines and supplements, and any recent illness or pregnancy that may affect interpretation.
   4. Paste the report, context and the prompt into ChatGPT, Claude or Gemini, then ask it to produce the requested plain-English explanation without identifying a disease.
   5. Compare the chatbot's copied values, units and ranges character by character with the original report, and delete any explanation based on a copied or transcribed error.
   6. Send the explanation and its list of questions to the clinician who ordered the tests, and ask them what the results mean in your full clinical context.
   7. If you have urgent or worrying symptoms, contact NHS 111 or use 111.nhs.uk rather than waiting for a chatbot explanation.

   Prompt

   Explain the blood test report below in plain British English. First copy each test name, result, unit and laboratory reference range exactly as supplied, and say if anything has been copied ambiguously. Then explain what each test generally measures and whether the result is below, within or above this laboratory's stated range. Do not identify a disease, predict my future health or recommend treatment, supplements or changes to prescribed medicines. Do not treat a reference range as a diagnosis, and do not compare it with a different laboratory's range. State clearly which conclusions cannot be drawn from these results alone. Ask me to contact the clinician who ordered the tests for interpretation in my full context. If the symptoms I describe sound urgent or worrying, tell me to seek NHS 111 advice and do not try to settle the urgency yourself. End with a short list of precise questions I can ask my GP or other clinician. I have removed names, dates of birth, NHS numbers and other identifying details.
   
   Basic context: [age range], [sex if relevant to the report], [reason the tests were ordered], [relevant symptoms and when they started], [medicines and supplements], [pregnancy or recent illness if relevant].
