Prenatal testing for chromosomal and other genetic
abnormalities are well established. Conventional
cytogenetic, molecular cytogenetic, and molecular
genetic analyses are performed on amniotic fluid to
identify chromosomal trisomes and mutations
associated with inherited disorders such as sickle cell
disease, cystic fibrosis, and other disorders.
FISH
testing for trisomes and sex chromosome aberrations can
be performed for rapid diagnosis.
