The results can be seen in men and women, and the accuracy is still very high. So, what do you think of men and women in Tang's screening results? In fact, it's just a rumor. Don't be convinced about pregnant mothers.
What do you think of men and women in Down's screening
Down's screening is just a routine test for pregnant women during pregnancy. There is no scientific basis to link this test with the identification of fetal gender. If parents must want to know the sex of the fetus, it is & beta; - HCG value and AFP value that have some effect, but the result can not be 100% accurate.
What do you think of men and women in the results of Tang screening
1. In & beta; - hCG's mom test results, if the value is below 0.4, boys are more likely; if it is above 1.0, girls are more likely; if it is 0.4-1.0, then men and women are equally likely.
2. The combination of & beta; - hCG and AFP can improve some accuracy. The lower the mom value of & beta; - hCG, the more likely it is to have a boy. Β - the higher the mom detection value of hCG is, the lower the mom detection value of AFP is, the greater the chance of having a girl.
3. In the serum of Down's fetus, whether male or female, the detection value of & beta; - hCG is on the high side, while the detection value of AFP is on the low side. In addition, the case of Down's false positive is the same.
Above through some examination data judgment check fetal men and women's practice, only as a reference, is not completely accurate. For the parents of newborns, the above judgment methods can only be used to satisfy curiosity, not as a practical standard basis.
Is down's screening accurate for men and women
1. With the current medical level, the accurate method to identify the fetus is male or female is to use B-ultrasonic observation to check the fetal genitalia. The second is amniocentesis, and then we can do chromosome detection to judge.
2. In addition to the above two methods, any other method to determine the sex of the fetus, whether it is handed down in the past or various prediction methods that have arisen in recent years, is completely without scientific basis, all of which are the 'experience' caused by some coincidence, all of which are the same reason as sour girls.
3. If you have to know the sex of the fetus, there is only one way now, that is to trust the relationship and find an acquaintance. Please ask the ultrasound doctor to show it, otherwise the doctor will not tell the sex of the fetus.
It's impossible to accurately judge the sex of the fetus through Tang sieve. Now men and women are equal. As long as the child is healthy and intelligent, it's more important than anything else. Moreover, the current B-ultrasonic examination, because the hospital has very strict regulations, is strictly prohibited to inform parents of the sex of the fetus.
