The decision to be tested is a personal one. You may wish to be tested if you are concerned that you or your partner might be a carrier of a disease that is on the test panel. Being a carrier is more likely if you have a family member with the disease.
Some people decide to be tested to know their chances for having a child with a disease or for passing an abnormal gene to their child.
Carrier tests are expensive. Another factor that may guide the decision to have the tests is whether the cost of the tests is covered by your insurance company.
If you find out you are a carrier of one of these genetic disorders, other members of your family (such as your brothers and sisters) may want to get tested, too.
