Question
“Since the facial features already match those of Down syndrome, what is the probability of having Down syndrome? Is there still a need for a chromosomal test?”
Answer
“Distinctive appearance is one of the diagnostic indicators for Down syndrome. According to your description, the facial features align with Down syndrome symptoms. However, chromosomal testing is still necessary because facial features are only one of the manifestations, and they cannot alone confirm a chromosomal abnormality. It is recommended to undergo a detailed examination and take note of rest.”
