When Down's screening, the information in the application form was not completely filled in, and then the information was reported to them, and the result was available. Can I rest assured of such screening results? The result of Tang screening is the result of comprehensive calculation through some basic information such as the age, weight and diabetes of pregnant women and serological indicators in blood samples. The information that the hospital wants to do B-ultrasound should be to calculate your gestational age with your B-ultrasound information, and then combine the previous information to get the risk result.

Tang sieve is screening, not diagnosis. Informed consent must be obtained before screening. Doctors should also explain to you that screening has a certain false positive rate and detection rate. Generally, the false positive rate is controlled between 5% and 7%, and the detection rate reaches 70%, but there is no guarantee that there will be false negatives.

But we should know that only a few of the high-risk results are real birth defects, and most of them are false positive. Therefore, pregnant women should not be too nervous when screening high-risk results to confirm whether the information is accurate (including B-ultrasound information), and doctors will also recommend high-risk results for further diagnosis.
