MSAFP值常用于预测胎儿的开放性神经管缺损,也用于预测其他疾病。它对预测Down综合征的应用,做为新的开端正在研究中。该实验是一种好方法,但仍有不足之处,检测中会出现假阴性,假阳性的结果。因此,该实验不是一种绝对准确有效的试验。为了有效地利用这一试验,目前需要在足够数量和随访过程中建立能够应用的基线值程序,以对阳性试验做出解释。 MSAFP values ​​are often used to predict fetal open neural tube defects and are also used to predict other diseases. It is in the process of predicting the use of Down syndrome as a new beginning. The experiment is a good way, but there are still some shortcomings, the test will appear false negative, false positive results. Therefore, this experiment is not an absolutely accurate and effective test. To make the most effective use of this trial, there is a need to establish a baseline value program that can be applied in sufficient numbers and follow-ups to explain positive tests.
