Pregnancy a fetoprotein is high what does it mean

Alpha-fetoprotein is a glycoprotein produced by embryonic liver cells and yolk sac. During pregnancy, alpha-fetoprotein will reach a peak at 28 weeks to 32 weeks, and then slowly decline. If it is not particularly high, it is no problem. And pregnant women with diabetes will also cause alpha-fetoprotein to rise. In addition, the most important is if there are twins or fetuses with open neural tube defects, such as anencephaly or spina bifida will cause a significant increase in alpha-fetoprotein, which can be checked by B ultrasound. If there is an open neural tube defect in the fetus, the alpha-fetoprotein in the amniotic fluid is often more than ten times higher than normal. In addition, severe Rh blood group incompatibility in the fetus will also increase in pregnant women. It is necessary to seek medical attention and check regularly.
