A confident, polished AI answer is not proof that it is correct. The World Health Organization warns that large language models can produce health responses that sound authoritative but are completely wrong or contain serious errors. Treat an AI answer as a starting point for questions—not as a diagnosis, treatment plan, or substitute for professional care.
Use this checklist before relying on an AI health answer
- Break the answer into claims. Separate statements about symptoms, diagnoses, treatments, medication doses, interactions, risks, and urgency. Ask the chatbot to identify its sources and when the information was current, but do not treat its citations or self-assessment as verification. The WHO describes why: plausible-sounding health responses can still contain serious errors. WHO, 16 May 2023.
- Open the sources and check what they say. Follow each important citation to the original source. Confirm that it exists, addresses the same question, and actually supports the chatbot’s claim. Look for independent corroboration from reputable sources, such as official health agencies, medical schools, and established professional or nonprofit organizations. NIH consumer guidance recommends checking original sources, evidence references, reviewer credentials, and corroboration. NIH Office of Dietary Supplements guidance, reviewed 4 May 2022; MedlinePlus guidance, updated 26 February 2024.
- Check who is responsible and what they stand to gain. For linked material, look for the author or reviewer, relevant expertise, review process, funding, purpose, advertising, and product sales. Be wary of cure promises, dramatic claims, unsupported product pitches, or testimonials presented as evidence. These checks apply to the sources and commercial context around an AI answer: a generated response may not have a human author or conventional editorial review. A citation, by itself, does not prove that a claim is right.
- Check dates and whether the evidence fits. Find when a source was published, reviewed, or updated, and check current official guidance when advice may change. For research claims, consider the study design, whether it involved people or animals, the number and characteristics of participants, duration, and funding. A finding from a particular study or population may not apply to someone with different circumstances or medical history.
- Protect personal information. Before entering symptoms, diagnoses, test results, medication lists, or identifying details, read the AI service’s privacy policy and data-use terms. Avoid sharing sensitive information if the service does not clearly explain what it collects and how it uses or retains it. WHO flags risks to sensitive health data shared with large language model applications; NIH guidance also recommends understanding a site’s privacy practices before sharing personal information. WHO; NIH Office of Dietary Supplements.
- Take personal decisions to a healthcare professional. Use information you have checked to prepare questions, not to make a diagnosis or change treatment on your own. If the answer could affect medication use, treatment, or whether you seek care, ask a qualified clinician. MedlinePlus advises discussing health information with a provider before relying on it; a clinician can help determine whether it applies to you. MedlinePlus.
How to verify a claim in practice
Suppose a chatbot says, hypothetically, that a particular treatment is appropriate for a symptom and cites a health page. Do not assume the citation backs the recommendation just because it appears beneath the answer. Open the page and check whether it discusses that treatment, symptom, and relevant population; look at when it was reviewed; and compare it with another reputable source. If the sources do not support the claim, are outdated, or address a different situation, treat the AI answer as unverified and ask a clinician rather than acting on it.

What AI guidance does—and does not—establish
WHO’s guidance on large multimodal models, published 25 March 2025, discusses generative AI techniques and potential health applications. It does not establish that any particular general-purpose chatbot is safe, accurate, or clinically validated for a specific use. WHO, Ethics and governance of artificial intelligence for health. There is no single accuracy percentage that can establish whether an AI health answer is trustworthy: performance depends on the system and version, task, population, and evaluation. Judge the individual claim by its evidence and seek professional advice for decisions about your care.
