Patient's question:
Can cord blood testing rule out Down syndrome?Doctor's answer:
Disease Analysis: Amniocentesis or umbilical cord blood tests can both rule out Down syndrome. Additionally, fetal chromosome karyotype analysis, chromosome genetic disease diagnosis, and gender determination can be performed. DNA from amniotic fluid cells can also be used for genetic disease diagnosis and metabolic disease diagnosis.Medical Advice: If you have not undergone Down syndrome screening or if the screening results are high-risk, it is recommended to have a check-up at a local hospital with the necessary conditions.
