How to Make a Differential Diagnosis List

Differential diagnosis is one of the great procedural innovations of modern medicine. It essentially applies the process of elimination to diagnosing ambiguous conditions. Proper diagnosis is of the utmost importance because a misdiagnosis can lead to an untreated condition or, worse, an improper treatment that proves fatal to the patient. Physicians apply differential diagnosis in tandem with more technological diagnostic tools to find the root of a patient's medical problem.
