NEUROMETER CPT TESTING

PATIENT GUIDE TO THE CURRENT PERCEPTION THRESHOLD (CPT) TEST

WHAT IS IT?

The CPT test is a diagnostic procedure used to measure the condition of your nerves.  CPT stands for Current Perception Threshold and is a painless test that does not involve needles.  You will be given a very small electrical stimulus that will determine the lowest level (or threshold) of stimulus you can feel.

WHY TEST MY NERVES?

The best way to determine the condition of your nerves is through the CPT test.  This gives your doctor valuable information about the health of your nerves.  Certain disease states and other conditions an impair nerve function which may result in damage to the nerves.

WHAT WILL THE DOCTOR DO WITH THE TEST RESULTS?

The doctor will gain valuable information from this test, which will help to determine the appropriate treatment for your condition.

IS THE CPT TEST PAINFUL OR DANGEROUS?

No, the CPT test is neither painful nor dangerous.  There are no needles involved and the electrical stimulus is very low.  As soon as you feel a sensation the stimulus is stopped.

HOW IS THE TEST CONDUCTED?

The CPT test is performed by a certified CPT Technologist, usually in your doctor's office.  A pair of small gold plated electrodes are taped to your skin at different sites on your body.  The Technologist slowly increases the intensity of the stimulus until you report feeling a sensation at the electrode site.  Your part in the test is to inform the Technologist whether or not you feel the stimulus.  You will be given a series of tests in order to find the least amount of stimulus you can feel.  Before beginning the CPT test, the Technologist will explain the procedure to you and will be happy to answer any questions you may have about the CPT test.

HOW LONG WILL THE TEST TAKE?

The usual time to complete a test is 30 to 45 minutes, although repeat tests generally go more rapidly.  The testing is performed in the doctor's office.  Your comfort and convenience are most important to the CPT Technologist who will make every effort to complete the test as quickly as is possible.

WHAT CLOTHING SHOULD I WEAR?

You may be asked to wear clothing that can be easily removed depending on the sites being tested.  You will want to determine if this is necessary before the test.

HOW OFTEN WILL THE CPT TEST BE PERFORMED?

Your doctor will determine how often the CPT test will be repeated.  This will depend on your condition.
