-At what stage of pregnancy is prenatal diagnosis carried out?
Prenatal diagnosis can be carried out in the 1st, 2nd or 3rd trimester depending on the stage at which an abnormality is suspected. Different tissues are sampled according to the gestational age, e.g.
  • Chorionic villus (which forms the placenta) at 8-12 weeks
  • Amniotic fluid (which surrounds the fetus) at 15-18 weeks
  • Cord blood (from the umbilical cord) at >18 weeks.
