Who should consider carrier screening, genetic counseling and prenatal testing?
Because carriers are normal, only accurate carrier testing can tell whether someone is a carrier. If both parents are found to be carriers for a disorder (or if one parent is a TS carrier and the other parent has an inconclusive TS test), prenatal diagnosis can tell whether the unborn fetus is affected. Genetic counseling can help families understand their risk of having an affected child and testing. How long does it take to complete the test(s)? Most carrier and affected individual tests can be completed within 7-10 working days. Prenatal testing takes approximately 2-3 weeks.
