Berg suggests that testing should only be done on a voluntary basis, fully informed, and under complete confidentiality. Berg suggests that this is satisfactory if only the person at risk is affected. More often than not, though, this is not the case. Diseases commonly affect those surrounding the individual as well. Siblings should then be told of potential risks.
Cystic fibrosis is another genetic disease being tested for.
The National Institutes of Health recommended that testing for cystic fibrosis be offered to couples trying to have children. The recommendation was that insurance cover the cost of testing. The question still remains as to whether or not health insurance will cover education and counseling. While industry has been busy marketing clinical genetic tests, it has also begun to lean towards the sale of home genetic tests. Myriad Genetics Inc. of Salt Lake City has offered BRCAnalysis, a kit which tests for mutations to the BRCA1 and BRCA2 genes.
