Huntington's Disease Genetic Test: What Is The Test
Content provided by Healthwise
What Is the Test?
You give a blood sample, which is screened for the gene change. As part of the test, a close family member—preferably a parent—also may have to give a blood sample. That person's DNA is studied to look for the disease. Testing a family member also may be important in case your family's DNA is unusual in some way that might affect the test result.
