How we create our content
Symptomatik exists to make health information clear, accurate, and trustworthy. Every page is built to the standards below. If a page ever falls short of them, that is a bug we want to fix — see Corrections at the end.
Every page cites its sources
We do not ask you to take our word for it. Each explainer is grounded in published, authoritative evidence, and the sources are listed on the page itself — not hidden. We prefer, in order:
- National and international clinical guidelines (for example WHO, NICE, USPSTF, and specialty societies such as the ADA, the Endocrine Society, and cardiology bodies).
- Authoritative reference texts and professional laboratory references.
- Peer-reviewed systematic reviews and primary research for specific claims.
- Patient-facing authorities (such as NHS or MedlinePlus) for plain-language framing — never as the sole citation for a clinical claim.
We avoid single studies presented as settled fact, secondary aggregators, and content-farm material.
How we research and review
Each page goes through a deliberate, multi-stage process before it is published:
- Research against the source hierarchy above.
- Drafting in plain language by a medical writer.
- Independent review along four separate dimensions — structural quality, factual accuracy and source-grounding, voice and readability, and search clarity — before anything ships.
The goal of that process is that what you read is both easy to understand and verifiably correct.
Written in plain language
Health information is only useful if you can actually use it. We explain tests, results, and conditions the way a careful clinician would explain them to you — calmly, without a wall of jargon, and in words you can take to your own appointment.
Reference ranges vary — use the range on your report
Laboratory reference ranges differ by lab, by method, by units, and by country, and they shift with age, sex, and pregnancy. Any ranges we show are illustrative. The range that matters for your result is the one printed on your own report.
Information, not diagnosis
Symptomatik provides general health information. It is not a diagnosis, and it does not replace a consultation with a qualified clinician. We do not provide individual medical advice, drug dosing, or treatment instructions. If you may be experiencing a medical or mental-health emergency, contact your local emergency services immediately. See our Medical Disclaimer for the full statement.
Independence
Our content is written to serve the reader. What we recommend you consider — a test, a follow-up question, a conversation with your clinician — is never influenced by a commercial relationship.
Written for each language, not machine-translated
Symptomatik is published in English, Polish, and Spanish. Each language version is written natively for its audience — including locally relevant reference framing and care-system context — rather than machine-translated from English.
Keeping content current
Every page shows when it was published and last updated. We review content on a schedule and whenever the underlying guidance changes, prioritising the topics where clinical guidance moves most often.
Corrections
If you believe something on Symptomatik is inaccurate or out of date, we want to know. Accuracy is the entire point of this site, and reader-reported issues are reviewed against our sources.
