Genetic Procedures

• Chorionic villous sampling (CVS). We perform only transabdominal CVS which is the safest procedure at 11-12 weeks (this an invasive procedure with low risk for pregnancy loss).
• AmniocentesisAmniocentesis:
  A procedure in which a sample of amniotic fluid is drawn out of the uterus through a needle inserted in the abdomen, used to detect genetic abnormalities or the baby's sex.  (this is an invasive procedure with low risk for pregnancy loss done after 15 weeks).
• Fetal Blood Sampling (PUBS) (this is an invasive procedure with higher than AmniocentesisAmniocentesis:
  A procedure in which a sample of amniotic fluid is drawn out of the uterus through a needle inserted in the abdomen, used to detect genetic abnormalities or the baby's sex.  pregnancy loss risk)
• Nuchal Translucency and first trimester genetic screening for Down syndrome (non-invasive, no risk to the baby). This is a test that combines ultrasound assessment of the baby's nuchal translucency (NT), nasal bone, dutus venosus DopplerDoppler:
  Often used as a non-invasive method of measuring blood flow in humans.  and maternal blood testing.
• Level II (targeted anatomical and genetic marker) ultrasound {a negative such ultrasound at Kofinas Perinatal reduces the risk for ChromosomalChromosomal:
  Of or relating to a chromosome;"chromosomal defect"  defects (Down syndrome and other TrisomyTrisomy:
  The condition of having three copies of a given chromosome in each somatic cell rather than the normal number of two. ) by as much as 80%.
