Buerger's test
System: General & Eye–Ear Signs · All general & eye–ear signs
What it is — and how it is elicited
The legs are raised until they blanch pale, then lowered and hung down: they slowly flush, sometimes with a dusky red 'sunset' colour, in arterial insufficiency (dependent rubor).
What a positive finding suggests
Associated with significant peripheral arterial disease of the legs.
◈ Behind the name
Leo Buerger (1879–1943), Austrian-American physician and urologist.

Please note: This page is an educational reference about clinical examination signs. A clinical sign supports — and never replaces — a full clinical evaluation, examination and appropriate testing. A sign being present does not by itself prove a diagnosis, and an absent sign does not rule one out. If you have symptoms that worry you, see a health professional.
