Perhaps no component of medical care is more important to subsequent care than
establishing a diagnosis. From this step decisions emerge about
treatment, prognosis, and use of health resources. Clinicians depend on
many types of information to establish a diagnosis including, for
example: history of angina and coronary artery disease; physical
examination finding of hard testicular lesion and cancer; radiographic
results showing apple-core colon lesion and cancer; electrocardiogram
results showing Q waves and myocardial infarction; and laboratory test
results finding elevated serum creatinine and uremia.
