Differential Diagnosis

Differential diagnosis is the discipline of keeping multiple possibilities open while collecting better evidence.

Working Method

1. Start with the main symptom cluster.
2. Separate urgent possibilities from routine ones.
3. Compare similar conditions.
4. Look for contradictions.
5. Decide what information is still missing.

AI Opportunity

AI can support differential diagnosis by organizing possibilities, reminding clinicians of red flags, and summarizing evidence. It should never replace professional examination.
