What is Arterial Testing?

Arterial Testing (commonly also known as a Peripheral Arterial Study) is a test of the arteries that supply blood to your arms and legs. Generally the test is ordered to evaluate either the Upper Extremities (arms) or Lower Extremities (legs). For the test, a highly-skilled technologist uses blood pressure cuffs to measure pressures often at multiple places in your arms and/or legs. Ultrasound (sound which can not be heard) may also be used to take pictures of your arteries.

Preparation For The Test.

LOWER EXTREMITY STUDIES ONLY:

  • Have nothing to eat or drink for 12 hours before the test. Why do I need to fast?
  • No smoking or chewing gum for 12 hours before the test.
  • Your medications may be taken as usual, with small sips of water.
  • Plan to be here for 1-1 ½ hours for the test.
  • Special instructions for patients with diabetes: Please speak with the physician ordering the test regarding whether or not to take your diabetes medications or injections that morning since you are unable to eat before the test.

    • What To Expect.

    For your test you may be asked to remove some garments (such as pants, shoes, and socks for lower extremity exams). You will be given a sheet or gown with which to cover-up and asked to lie on your back for the exam. Blood pressure cuffs will be used to measure pressure in various locations, likely before and after some light exercises. Ultrasound pictures may then also be recorded requiring a microphone-like device (transducer) held against your skin to record the pictures.

    Preparation For The Test.

    UPPER EXTREMITY STUDIES ONLY:
    There is no need to do anything different from your normal routine to prepare for your Upper Extremity Peripheral Arterial Study. You may eat a normal meal before your test and take all of your medications (if any).
