In a patient with normal patent arteries, the color should return to the palms relatively quickly ( within 10 seconds) after the release either artery. If pallor persist within the palm after the patient unclenches his fist and one of the arteries is released, then the test is positive and indicative of an occlusion within the artery that is being released. For example, if the radial artery is being compressed and palmar pallor persists then that is indicative of compromised blood flow of the ulnar artery. The same is true if the ulnar artery is compressed and palmar pallor persists then the compromised blood flow is in the arterial artery.
