Which term describes the consideration of multiple possible diagnoses before a final diagnosis is established?

• A. Differential diagnosis
• B. Absolute diagnosis
• C. Definitive diagnosis
• D. Conclusive diagnosis

Answer: (A)

Differential diagnosis is the process of weighing multiple possible causes for a patient’s presentation before arriving at a final diagnosis. It means you list several likely conditions, use clues from history, exam, and initial tests, and then narrow down to the most probable one. This approach helps avoid jumping to a single conclusion too early and guides appropriate treatment and further testing.

In the field, patients often present with symptoms that could fit several emergencies. A differential helps you prioritize interventions, decide what monitoring or tests to pursue, and determine the most suitable destination for care.

The other terms imply a final or proven conclusion. Absolute, definitive, and conclusive diagnoses describe a final determination, which isn’t typically made at the initial assessment when multiple possibilities must still be considered.
