Patient's question:
A newborn baby needs to have this check, right? Or can babies who are not yet adults also have this check? Is the Down syndrome screening related to age? Or does it mean that the older the age, the less effective it becomes?Doctor's answer:
Down Syndrome Screening and Age Regarding Down syndrome screening, it is generally recommended to be done before the age of 35. Because age is equivalent to or greater than 35, if Down syndrome screening is performed, it is very easy to have false positives or false negatives. Therefore, there are now regulations stating that if the age reaches 35, Down syndrome screening is not performed directly, but prenatal diagnosis is conducted, because the older the age, the higher the relative rate of fetal abnormalities.
