These analyses include testing for newborn susceptibility to different genetic diseases, diagnostic testing for genes that cause disease, forensic testing, research testing and predictive testing. 2. Home-brew genetic tests are manufactured and performed by the laboratory that ultimately uses the information. These tests are not regulated by the FDA and would be much harder to regulate than third-party testing. Many genetic tests fall into this category. 3. The workers would be extremely unlikely to test positive for the disease because first of all, it is autosomal dominant and would have likely manifested itself earlier in the family’s history.

Diagnosis is done by looking at family history, genetic testing looking for more than 36 repeats of the CAG nucleotide base repeats, and looking for symptoms associated with the disease....
