Question
How to Test if a Child Has Down Syndrome?
Answer
The primary characteristics of children with trisomy 21 include intellectual disability, delayed physical development, and a unique facial appearance. A peripheral blood chromosome test is required for diagnosis, which can typically be conducted at a third-level hospital. Diagnosis is usually made based on clinical symptoms, but for mosaic Down syndrome, chromosome testing is even more crucial. Currently, there are no additional treatment methods available, and early feeding and care can help promote the child’s growth and development.
