What is this test? And what does it indicate?
Everyone got it right, here is how you do it: The patient is asked to clench both fists tightly for 1 minute at the same time. Pressure is applied over both radial arteries simultaneously so as to occlude them. The patient then opens the fingers of both hands rapidly, and the examiner compares the colour of both. The initial pallor should be replaced quickly by rubor. The test may be repeated, this time occluding the ulnar arteries. Allen's test looks for abnormal circulation. If color returns quickly as described above, Allen's test is considered to demonstrate normal circulation. If the pallor persists for some time after the patient opens their fingers, this suggests a degree of occlusion of the uncompressed artery. From: @medicalcortex
