Serologies and Autoimmune Testing for the Dermatologist

Serologic evaluation plays a pivotal role in diagnosing and monitoring autoimmune diseases in dermatology, but tests must be ordered judiciously to inform care without causing confusion or unnecessary intervention. This session will outline the dermatologist’s framework for selecting and interpreting autoimmune serologies, emphasizing clinical context, pre-test probability, and collaboration with rheumatology colleagues. Attendees will learn to distinguish between supportive versus diagnostic value, manage uncertainty, and align testing strategies with evolving guideline-driven algorithms.
