胎儿羊水采集方法


羊水采集方法介绍

胎儿亲子鉴定的方法有两种,第一种是胎儿绒毛采集,这种方法相对比较大有千分之三的几率会流产,不太建议使用,而另外一种就是羊水亲子鉴定,这种方法危险系数相对比较小,如果不做无创亲子鉴定,建议使用这个方法鉴定。


胎儿羊水采集注意事项手续及流程:

所有人的体内都会有细胞核细胞都可以用来做DNA检测,其中较为常见的就是血液,血痕,指甲,头发,口腔拭子等,其他的还有牙齿,骨,肌肉,精斑,和胎儿的羊水都可以用来检测DNA。本中心采用的是最新的DNA检测方法,整个过程采样便利,快捷,保密,无创。

胎儿羊水亲子鉴定

为你母子安全,胎儿羊水的采集应该在16周以上,比较好的采集时间在19-23周之间,且需要在正规三甲医院请专业的医生来采集,以确保母子平安,胎儿的羊水的采集均由专业的妇产科医生做B超监控采集,而且不能采太多只能采集一点点,基本不会对胎儿有造成影响,拿羊水做DNA鉴定需要提供母亲的DNA样本作为对比。


注意:本中心只需要8毫升的羊水,抽取出来的羊水应清澈透明,不含有母亲的血液成分,羊水取好之后,应该尽快送到本中心,如果天气比较热,应该准备好冰袋冷冻保存,与母亲DNA样本同时提供。


亲子鉴定的方法有各种,但是基本都是按照孟德尔遗传学定律来进行,运用现代科技仪器进行生物技术检测,对比鉴定人的DNA片段,通过对比DNA中的多个遗传基因信息,对结果进行分析,最后得出结果。


如果是邮寄方式,为了避免样本丢失,可以使用快递方式邮寄,邮寄前请提前联系本中心,寄的时候记得填写好样本归属人,如果有特殊要求也可以提前告知,如果您有任何困难都可以直接联系本中心,欢迎来电咨询。



Methods of amniotic fluid collection


There are two methods of fetal paternity test. The first method is fetal villus collection. This method is relatively large and has a three thousandth chance of abortion. It is not recommended to use it. The other is amniotic fluid paternity test, which has a relatively small risk coefficient. If non-invasive paternity test is not conducted, it is recommended to use this method.


Procedures and procedures for fetal amniotic fluid collection:


All people have nuclear cells in their bodies that can be used for DNA testing. The most common ones are blood, bloodstains, nails, hair, mouth swabs, etc. others can be used to detect DNA in teeth, bones, muscles, seminal plaques, and amniotic fluid of the fetus. The center uses the latest DNA detection methods, the whole process of sampling is convenient, fast, confidential, non-invasive.

Paternity test of fetal amniotic fluid


For the safety of your mother and child, the collection of fetal amniotic fluid should be more than 16 weeks, the better collection time is between 19 and 23 weeks, and professional doctors should be invited to collect the fetal amniotic fluid to ensure the safety of mother and child. The collection of fetal amniotic fluid is monitored and collected by professional obstetricians and gynecology doctors, and can't take too much, only a little can be collected, which will not affect the fetus Well, we need to provide a mother's DNA sample for comparison.


Note: this center only needs 8 ml amniotic fluid. The extracted amniotic fluid should be clear and transparent, and does not contain the blood components of the mother. After the amniotic fluid is taken, it should be sent to the center as soon as possible. If the weather is hot, ice bags should be prepared for cryopreservation, and the mother's DNA samples should be provided at the same time.


There are various methods for paternity testing, but they are basically carried out in accordance with Mendelian law of genetics. Modern scientific and technological instruments are used to carry out biological test, and the DNA fragments of human beings are compared. The results are analyzed by comparing the information of multiple genetic genes in DNA, and finally the results are obtained.


If it is by mail, in order to avoid the loss of samples, express mail can be used. Please contact the center in advance before mailing. Remember to fill in the ownership of samples when sending. If you have any special requirements, you can also inform us in advance. If you have any difficulties, you can contact the center directly. Welcome to inquire.
