Allen Test for Blood Flow: Purpose, which is a negative indication for catheterisation or removal of the radial arteries, a chemical reagent used in such a procedure c, and it’s founder’s name is Edgar Van Nuys Allen he has described the test in 1929, this is a simple way to measure how well blood flows in your hand, after compression of both the ulnar and radial arteries followed by repeated clenching of the fingers to squeeze out the blood, 3 The correct technique involves the patient making a fist for 30

BACKGROUND: Allen’s test is widely used to assess the ulnar collateral blood supply of the hand before radial artery harvest for coronary bypass surgery, Allen first described his test in 1929 but did not indicate a time period after which a test should be
The modified Allen’s test (A.T.) is used to prove the adequacy of the blood supply through the ulnar artery to the hand, This study was performed to determine the optimum cut-off point for a positive Allen’s test and the clinical reliability of Allen’s test in this role.
,A positive bup on a drug screen test is a positive result for buprenorphine, The test is considered normal if, The test is easy to carry out, A positive Allen Test shows that the patient does not have a dual blood supply to the hand, 2 His original description of making a fist with the RA occluded for 1 minute followed by extending the fingers and watching for return of color was later modified and is now called the modified Allen test (MAT), Gordon Groh”>
The mechanism of why a clinical Allen’s test would be a false positive while the surgical Allen’s test potentially has a higher specificity is not clear, However, Failure of blood to return to the palm and fingers when the hand is opened indicates obstruction of the blood flow in the artery that has not been compressed.
Allen’s test is also used to assess the adequacy of ulnar collateral circulation to the hand, b, & Results
Also called a modified Allen test, surgical exposure of the radial artery with direct occlusion eliminates potential ambiguities of if a vessel is truly occluded or not as may be seen in a clinical Allen’s test.
Allen’s test, It is done prior to radial artery cannulation for pressure monitoring, the normal or a slightly more pronounced red color of the palm of the hands returns within < 10 sec after release
Allen’s Test: Physical Exam
Positive result: Using Change in Skin Color : Within 3-5 sec the palm becomes flush and ulnar artery is considered patent, Abnormal (negative) Your hand remains pale and cold, Normal (positive) Your hand quickly becomes warm and returns to its normal color, Buprenorphine is often used as a tool to lessen the addiction of opiate addiction, Additional tests for thoracic outlet syndrome include: Roos Test; Adson’s Test / Adson’s Maneuver; Involved Structures
Barbeau test – Allen’s test using pulse oximetry Allen’s test is often used to assess the efficacy of collateral circulation in the hand through the superficial and deep palmar arches, Ulnar artery can supply blood flow if radial artery is damaged or becomes occluded during the procedure.
