WikiDoc Differential Diagnosis Project — Mission Statement

Thank you for your interest in the WikiDoc Differential Diagnosis Project.

Differential diagnosis is the process of distinguishing a particular disease or condition from others that present with similar clinical features.

A differential diagnostic procedure is generally a systematic diagnostic method used in each individual patient based on their specific condition to identify the presence of a disease entity where multiple alternatives are possible. This method is essentially a process of elimination or at least a process of obtaining information that shrinks the "probabilities" of candidate conditions to negligible levels, by using evidences such as symptoms, patient history, and medical knowledge.

The Differential Diagnosis Project aims to integrate current body of medical literature in the new era of differential diagnosis into conjoined, systematic pages where the availability of comparing between different possibilities be possible for diagnostician, in conformity with practice guidelines, consensus statements, systematic reviews, and expert opinions.

Educational content provided herein is not intended to supplant but supplement clinical judgment. In light of the variability in epidemiological contexts and resources available to diagnose a disease, adjustment in diagnostic approach may be required to optimize patient care.
