Rumble-leede-test

Capillary resistance test. The Rumpel-Leede test detects disorders caused by thrombopenia and bleeding as a result of vascular disorders.

Evaluation:

Negative test: no petechiae

Positive test: with normal platelet count V.a. vascular fragility. No differentiation between thrombocytopenic and vasculitic bleeding possible!

Apply (as for blood pressure measurement) a blood pressure cuff to the upper arm. After inflating the cuff, the pressure (pressure should be 1o mm above diastolic pressure) is held for 5 minutes; after deflation, the arm is held still for 10 minutes. During this time the number of petechiae is determined. With increased capillary fragility, petechiae distal to the blood pressure cuff (elbow) occur at a cuff pressure of 50 mm Hg > 5.
