If the size of the double neck diameter does not meet the standards and developmental requirements, parents may be particularly concerned, fearing that the baby may have developmental abnormalities or other abnormal manifestations, such as Down syndrome symptoms. Everyone may want to conduct further examination. What is the suspected size of the biparietal diameter for Down syndrome?
The size of the biparietal diameter is not significantly related to Down syndrome, so the size of the biparietal diameter cannot directly determine Down syndrome. In general, the genetic inheritance of Down syndrome is related. Some babies may have chromosomal or genetic mutations in their mother's womb, leading to symptoms such as Trisomy 21 syndrome, which can cause significant damage to the brain.
To prevent the symptoms of Down syndrome, comprehensive screening can be conducted, but it is not necessarily necessary to do these tests. However, some parents can conduct healthy screening programs to ensure good developmental outcomes and reduce the interference of various diseases in their babies, which should have a good effect.
In addition, during the process of Down syndrome screening, everyone still needs to be rigorous in dealing with various things that need to be paid attention to, such as determining the screening time and understanding the various preparations for screening. Generally, Down syndrome screening is performed around two to five months of pregnancy, and the results of these screening tests can be obtained quickly. Everyone should listen to the doctor's explanation.
