Patient's question:
NoDoctor's answer:
The Down syndrome screening is an early test for chromosomal disorders such as trisomy 21 and trisomy 18 to reduce the birth of malformed infants. However, the initial screening only estimates the risk factor. If the risk is high, further diagnostic tests should be conducted, such as: amniocentesis to extract fetal cells and test chromosomes, or amniocentesis to examine the fetal appearance for any abnormalities. This will help to confirm the diagnosis, rule out malformations, and ensure your baby's health.
