Down Syndrome Screening

Down syndrome is a genetic condition that can be screened prenatal or confirmed through diagnostic tools post natal.Prenatal initial screening can be done as early as

12 weeks when nasal bone and nuchal translucency scan can be done by ultrasonic 

investigations and if screening comes high risk,then chorionic villus sampling can be 

early diagnostic method.Double Marker,Triple Marker and Quadraple Markers are blood markers that pathologically rules out the risk. The last confirmatory test comes out to be amniocentesis.Amniocentesis is the most near to confirmatory test one can go through to rule out the down syndrome status of unborn child.The confirmatory tests like chorionic villus sampling and amniocentesis carry risk of loosing the pregnancy.But this risk is always less than the risk to face the hardship to become parents of a compromised child.
