Prenatal diagnostic tests are tests that are able, in most cases, to give you a definitive ‘yes’ or ‘no’ answer about whether a pregnancy is affected with a variety of chromosome and genetic conditions.
While these tests are able to provide a lot of definitive information, there is a risk for miscarriage. The level of risk depends on which test is being done and the level of experience of the doctor performing the procedure. For tests that can still provide some information, but carry no risk for miscarriage, see Prenatal Screening Tests.
It is also important to know that prenatal diagnostic tests are always optional. You never have to undergo any prenatal testing if you do not wish to. Anyone who is having prenatal testing should have access to all of the necessary information to make an informed decision about what is right for them and their family.
