Sample User Question back to top

What laboratories in the U.S. test for Huntington's Disease? What is the sensitivity of DNA-based testing?

Analysis/Comments back to top

GeneTests provides the clinician with an efficient means to locate genetic testing laboratories. Because registration with GeneTests is voluntary, there may be other laboratories in your community or state that provide testing but are not listed in this directory.

Additional Notes back to top

The question is phrased using the familiar phrase, Huntington's Disease. The actual GeneReviews record uses the MeSH subject heading, Huntington Disease. Like other online search services, the familiar apostrophe s must be removed to retrieve search results. As many users will phrase the question using the familiar name, Huntington's or Alzheimer's, it is important for end users to learn to remove the apostrophe s.
