Reasons For Genetic Testing
Types of Genetic Tests
- There are many different kinds of genetic tests. There is no single genetic test that can detect all genetic conditions. The approach to genetic testing is individualized based on your medical and family history and what condition you’re being tested for. Single genetesting. Single gene tests look for changes in only one gene. Single gene testing is done when your doctor believes you or …
Testing For Changes Other Than Gene Changes
- Chromosomes. DNA is packaged into structures called chromosomes. Some tests look for changes in chromosomes rather than gene changes. Examples of these tests are karyotype and chromosomal microarrays.
- Gene expression. Genes are expressed, or turned on, at different levels in different types of cells. Gene expression tests compare these levels between normal cells and diseased cells b…
