Quantitative Sensory Test



What is Quantitative Sensory Testing (QST)?

 

This is a test of your body’s ability to feel such things as temperature and vibration, especially in the parts of your body where you experience pain.

 

Why did my doctor order this test? 

 

Your doctor ordered a QST to see how well your nervous system works, in particular your small nerve fibers.  The test will help your doctor tell if there is damage to small nerve fibers, and if so, how much damage has occurred.  If the test is repeated, it will be a way for your doctor to watch for changes in your small nerve fibers function.

 

Is the QST painful? 

 

Some patients report only minor, brief discomfort at times during the testing.  The QST does not use needles or electric current.  The status of your nerves will be assessed through the use of warm, cool, hot, and cold temperatures and through vibration. 

 

How should I prepare for the test?

 

There is no special way to prepare for this test.  The test may take 1 to 2 hours.  This depends on the number of sites to be tested.  You should wear loose, comfortable clothing as it will be removed from the sites tested. 

 

Results will be sent to your doctor for review and are often ready in about one week.
