An evidence-based health platform.
Not a chatbot. Not a directory.
Elements84 helps readers understand reviewed health evidence, use practical decision tools with declared limits and read plain-English medical articles. It is designed to be read before, not instead of, a qualified healthcare professional.
Health information should reduce doubt, not multiply it.
Two readers can search the same question and end up with two very different answers. That is a failure of information design, not of medicine — and it makes it harder to act, harder to ask the right question, and harder to know when a number is a signal or a distraction.
Elements84 exists to make reviewed health knowledge easier to reason about. Fewer articles that a reader can act on. Fewer numbers presented without context. Fewer confident answers where the honest answer is "it depends".
Three surfaces. One evidence base.
Each surface is a first-class product. They share the same sourcing standards, the same limits framework and the same non-diagnostic framing.
Reviewed articles
Plain-English explainers on the questions patients actually ask — "normal ECG but chest pain", "high HbA1c with normal blood sugar", "positive ANA without autoimmune disease". Each article names its sources.
Evidence Search
A deterministic search across reviewed Elements84 content. Results are drawn from published articles and evidence summaries — no open-ended AI-generated medical advice, no invented references.
Health decision tools
Calculators, converters and estimators — plus full decision tools that state what the number does not measure, where it does not apply and when to talk to a qualified healthcare professional.
Four practices that hold the platform together.
These are the rules the editorial and product teams follow every time an article is published or a tool is upgraded.
Sources named, not implied
Every article, evidence summary and tool threshold traces to primary sources — WHO, IOM, ADA, ISSN, ACSM and peer-reviewed literature. Anything that cannot be sourced is not published.
Limits declared up front
Health decision tools state what the formula measures, what it does not, where the population thresholds do not apply and when the result needs professional context — as part of the result, not hidden in a disclaimer.
Non-diagnostic framing
Results are presented as screening ranges and decision context. Elements84 does not diagnose, does not prescribe and does not replace a qualified healthcare professional.
Privacy-conscious tools
Health decision tools calculate locally in your browser. Your inputs are not sent to any server, no account is required and analytics never receive your calculator values.
A number is a starting point — not a conclusion.
Every health decision tool on Elements84 states what it measures, what it does not, and where the standard thresholds do not apply. Use the result alongside symptoms, laboratory context, personal history and the judgement of a qualified healthcare professional — not as a stand-alone verdict.
What we choose not to be.
Being honest about the boundary matters as much as being useful inside it.
- Diagnose conditions or provide treatment plans.
- Prescribe medication, adjust dosages or replace clinical follow-up.
- Interpret an individual laboratory report against a personal medical history.
- Provide emergency medical services, triage or crisis support.
- Publish content or thresholds that cannot be traced to a primary source.
Read the standards behind every article and tool.
Sourcing rules, review workflow, correction policy and the categories of evidence we use — published openly.
The goal is clarity, not certainty.
Where the evidence is strong, we say so. Where it is uncertain, we say that too. Elements84 helps you leave a page knowing what you can act on — and what still needs a conversation.
