All three Down’s syndrome tests are low-risk means that all three Down’s syndrome tests are low-risk test results and the likelihood of having a Down’s syndrome baby is not very high.
The Down’s syndrome screening test can initially determine whether the fetus has conditions such as trisomy 21, trisomy 13, trisomy 18, and neural tube malformation. The tests mainly include: serum human chorionic gonadotropin, alpha-fetoprotein, and free estriol, etc. If all three tests are low-risk, it means that the likelihood of having a Down’s syndrome baby is not very high.
However, there may be errors in the screening results. Pregnant women need to take regular follow-up pregnancy tests under the guidance of professional obstetricians and gynecologists, do all the tests for malformations, and deal with any abnormalities in a timely manner.
