A negative Allen's test indicates that blood flow to the hand is adequate from the ulnar and radial arteries. During the test, the patient is asked to clench their fist while pressure is applied to occlude the ulnar artery; then, the hand is opened, and the color is observed. If the hand quickly returns to its normal color, the ulnar artery is patent, and the result is considered negative. This is important for assessing vascular supply before procedures like radial artery catheterization.
