Important Note

This test is only available to the University of Vermont Health Care clinics and hospital.

For arterial collection, the Laboratory recommends that the Modified Allen test be performed to determine that collateral circulation is present from the ulnar artery in the event that thrombosis of the radial artery should occur. Performance of the Modified Allen test should be documented in the patients' chart.
