What are the three types of genetic testing?
The following information describes the three main types of genetic testing: chromosome studies, DNA studies, and biochemical genetic studies.
Tests for cancer susceptibility genes are usually done by DNA studies..
What are the risks of genetic testing?
Generally genetic tests have little physical risk. Blood and cheek swab tests have almost no risk. However, prenatal testing such as amniocentesis or chorionic villus sampling has a small risk of pregnancy loss (miscarriage). Genetic testing can have emotional, social and financial risks as well.
How expensive is genetic testing?
The cost of genetic testing can range from under $100 to more than $2,000, depending on the nature and complexity of the test. The cost increases if more than one test is necessary or if multiple family members must be tested to obtain a meaningful result.

What genes are inherited from mother only?
And, mitochondrial DNA (or mDNA) is inherited strictly from the mom. Because mDNA can only be inherited from the mother, meaning any traits contained within this DNA come exclusively from mom—in fact, the father’s mDNA essentially self-destructs when it meets and fuses with the mother’s cells.
Does insurance pay for genetic testing?
