In brief: Yes
To determine whether someone has huntington's disease, a gene analysis can be done to detect whether or not a repeating-cag mutation is present on the huntington gene.
If the cag sequence in the gene repeats too many times, the gene is abnormal. A meeting with a genetic counselor before and after the test is recommended to determine need for the test and to discuss the results of the test.

In brief: There is but note:
Because hd follows an autosomal dominant pattern of inheritance patients who are at risk of inheriting it often look for a diagnosis.
The genetic test for hd consists of a blood test which counts the numbers of cag repeats in each of the hd genes. A positive result is not considered a diagnosis, since it may be obtained decades before the symptoms begin but gives you an idea of the risk for hd.
