What a differential diagnosis tree is.
A differential diagnosis tree is a branching framework for organizing possible causes of a clinical presentation. It begins with urgent features, then separates the history, signs and findings that can make one group of causes more likely than another.
It is useful for learning and case discussion because it makes the sequence of reasoning visible. It is not a diagnostic tool and cannot replace clinical assessment, testing, local protocols or professional judgment.

Common questions
What is a differential diagnosis tree?
It is a branching way to organize possible causes of a presentation using symptom features, clinical findings and urgency.
Is this a diagnostic or triage tool?
No. It is an educational and communication aid. Real patients need clinical assessment and applicable local emergency guidance.
Why do red flags appear first?
Potentially unstable findings may require prompt assessment before common or less urgent causes are considered.
Can I add test results to a tree?
Yes. In a teaching case, add relevant vital signs, examination findings or investigations as decision points.
