Question
Can umbilical cord blood testing rule out Down syndrome?
Answer
Both amniocentesis and umbilical cord blood testing can be used to rule out Down syndrome. They also allow for fetal chromosome karyotype analysis, diagnosis of chromosomal genetic diseases, gender determination, and genetic and metabolic disease diagnosis using amniotic fluid cell DNA. If you haven’t undergone a Down syndrome screening or the results are high-risk, it is recommended to check at a local hospital with the necessary conditions.
