Chorionic villus sampling is a form of prenatal diagnosis performed to determine chromosomal or genetic disorders in the fetus, by sampling the chorionic villus and testing it for chromosomal abnormalities, usually with fluorescence in situ hybridization or polymerase chain reaction. It usually takes place at ten to twelve weeks of gestation, earlier than amniocentesis or percutaneous umbilical cord blood sampling, and it is the preferred technique before fifteen weeks.
Facts
FAQs
Does the way chorionic villus sampling is done change the miscarriage risk?
Miscarriage rates are slightly higher when the test is done through the cervix rather than the belly.
Chorionic villus sampling can be done through the cervix, which is called the transcervical route, or through the belly, which is called the transabdominal route. MedlinePlus reports that miscarriage rates are slightly higher when the test is done through the cervix.
