Is there an age limit for Down syndrome screening?

Patient's question:

November 10, 2012 pregnancy, want to do Down syndrome screening, 39 years old this year

Doctor's answer:

Analysis of the condition: Hello: Down syndrome is a common chromosomal disorder. Children with this condition suffer from severe intellectual impairment and are unable to live independently. They are often accompanied by complex cardiovascular diseases and require long-term care from family members, which can impose significant mental and financial burdens on the family. Currently, there is no effective treatment for Down syndrome. If you do not have the conditions, it is best to undergo a Down syndrome screening. Once it is confirmed that the fetus has the disease, the option of terminating the pregnancy can be considered. Generally, the optimal time for Down syndrome screening is between the 15th and 20th weeks of pregnancy.
Advice: Hello: The risk of the fetus developing Down syndrome tends to increase with the mother's age. Based on your situation, it is recommended to undergo the screening between the 4th and 5th months of pregnancy, preferably on an empty stomach. Wishing you and your baby good health.
