Pregnancy

Amniocentesis

This is the diagnostic test (meaning: definitive test to confirm if fetus has Down’s syndrome). This can be done in the clinic.
Using ultrasound guidance, a fine needle is used to aspirate the amniotic fluid to check for the fetal karyotype (chromosome pattern). Should the above screening tests show a high risk of the fetus having Down’s syndrome, an amniocentesis should then be considered to confirm the fetus’ karyotype. This procedure can be done between 16-20 weeks of pregnancy. After the procedure, rest is recommended for a day at least.
