Down syndrome screening critical risk

Patient's question:

No

Doctor's answer:

The screening test provides a risk assessment value. The critical value is generally 1/270. Values above this are considered high risk, while those below it are considered low risk. Since 1/436 is less than 1/270, it is a low-risk result. However, the accuracy of the screening test is only about 70%, and a low-risk result does not necessarily mean the baby is healthy. Further tests are needed to confirm whether the baby is affected by the condition.
