Question
The Down syndrome screening test indicates a critical risk for trisomy 21, and the doctor has recommended that I undergo a non-invasive DNA test. However, I am 25 years old, and neither of my families has a history of genetic diseases. One of my friends also has a trisomy 21 ratio of 1:380, which is considered low risk for her. Do I absolutely need to have the non-invasive DNA test?
Answer
Hello, based on the key risks you described, the general risk is not very high. However, it is recommended that you undergo further examination. Removing malformations is relatively safe, and this test has little impact on the fetus, making it impossible to detect fetal malformations. It is best to cooperate with your doctor’s examination so that you can also feel at ease. Mid-term examinations are very important, and I suggest you still follow your doctor’s advice and undergo regular checks.
