Patient's question:
Test results: Down syndrome: 1:329 OSB: 1:27303 Trisomy 18: 1:50000 Should I have an amniocentesis? What kind of help do I need: Down syndrome screening reportDoctor's answer:
Your results are still within the normal range and do not require further testing. Combined risk value for Down syndrome screening: 1:329 is within the normal range. As long as it is higher than 1:250, which is within the normal range, further amniocentesis is not necessary. When Down syndrome screening is in a high-risk state, the mother should continue with further screening, such as amniocentesis, which is a good way to confirm whether Down syndrome is truly present in the child.
