In medicine, clinical acumen is used to achieve diagnosis, guide management and prevent disease. While for some diseases, diagnosis is reached with the assistance of objective tests, many conditions rely upon the use of clinical diagnostic criteria; Behçet's disease is one such case. In order to remain clinically relevant, as knowledge of a condition changes over time so too must its diagnostic criteria. Preferably, when new criteria for a disease are conceptualised it is through sound methodology, followed by a confirmation of accuracy by way of systematic validation and response to treatment. The most recently proposed revised International Criteria for Behçet's Disease for the diagnosis of Behçet's disease have been systematically validated and should replace the use of the clinically inferior International Study Group criteria, while not displacing the role of clinical judgement. Effort should now be invested in acquiring better understanding of the pathogenesis of the disease in the hope of developing a more objective test.
