Activity Description

The Allen test assesses collateral blood flow to the hands, generally in preparation for a procedure that can potentially disrupt blood flow in either the radial or the ulnar artery. These procedures include arterial puncture or cannulation and the artery harvest alone or as part of a forearm flap. A negative Allen test means that the patient likely does not have an adequate dual blood supply to the hand, which may present a contraindication to the planned procedure or at least suggest that further evaluation is necessary. This activity reviews the Allen test technique and discusses the interprofessional team's role in applying this maneuver to improve patient outcomes.


Target Audience

This activity has been designed to meet the educational needs of physicians.

Learning Objectives

At the conclusion of this activity, the learner will be better able to:

  • Identify the vessels evaluated by the Allen test.

  • Determine the indications for performing the Allen test.

  • Implement the technique for performing the Allen test.

  • Develop interprofessional team strategies for improving communication regarding the significance of a negative Allen test.
