Differential Diagnosis
The clinical process of comparing possible explanations for the same symptom pattern, then narrowing them with history, exam, testing, and judgment.
Plain English
A differential diagnosis is the doctor's short list of possible causes.
Why It Matters After 40
AI can list possibilities, but it cannot perform the full clinical process from a text box.
What To Do With It
Use AI's list to ask better questions. Do not treat it as a diagnosis.
Human Utility
- Know what the term means before uploading data into an AI tool.
- Separate explanation from medical interpretation.
- Bring trend data and context to the appointment instead of one isolated number.
Clinical Boundary
New, severe, or fast-changing symptoms need medical care, not a longer AI conversation.
