The way of exclusion is called Differential diagnosis
Evidence based medicine
It is the conscientious（谨慎的）, explicit （明确的）and judicious （有见解的）use of current best evidence in making decisions about the care of the individual patient It means integrating individual clinical expertise （临床专长）with the best available external clinical evidence from systematic research
Evidence based medicine
One need to:

Be conscientious: it requires effort and thought.
Be explicit: decisions will need to be backed up by good evidence
Relate to specific problems: it is not about a hypothetical
"average" case.

Integrate individual clinical experience: it does not denigrate
clinical skills in history taking, examination and diagnosis.

Look for current best evidence: the perfect study may not yet have
been published, written up or even commenced. We may have to
settle for something less rigorous, but be on the look out for new
research that will supersede older studies.
