Answer

Prenatal diagnosis is also available. The laboratory procedures employed in prenatal testing are sensitive and rapid. Prenatal testing must be accompanied with genetic and psychological counseling. Chorionic villus sampling can be performed at 8-12 weeks' gestation to obtain DNA. This low-risk procedure is safe. DNA from amniotic fluid cells can be examined at 16 weeks' gestation. Investigational attempts are ongoing to isolate fetal cells from maternal blood for DNA assay.
