Genetic testing can be quite expensive. The testing for one family member usually costs around $3,400. If a mutation is identified, other family members can be tested for the same mutation for about $500. If you are of Ashkenazi Jewish descent, the testing is more straightforward, and typically costs around $500-$600. Fortunately, many insurance companies cover the cost of genetic tests. You usually have to prove that you qualify for the coverage by offering specific information about your family history.
