头发样本采集方法


首先我们先要了解到,头发样本并非是像电视上面看的那样,直接用剪刀剪下来就可以,并非如此哦,现实版的头发样本是需要直接拔下来的,需要带毛囊,所以不要被电视节目给骗了,那么我们到底需要怎么去采集头发样本呢,以下就由本中心为大家介绍:


头发样本


1、准备好干净的纸巾,或者信封;


2、用手捉住头发大概在4CM左右的地方,用力拔出,以下子可以拔一根,看到清晰带上毛囊的即为合格样本,用同样的方法采集5根以上;


3、用准备好的纸巾包住头发,不能让头发的毛囊和毛囊碰到一起,前提条件,如果头发比较湿润先等待风干后再用纸巾包好;


4、写上相应的样本人员姓名身份,然后可以邮寄的方式寄到本中心,或者直接到本中心来也是可以做。


头发样本的好处:


1、不会受到时间的限制,而且采样方法比较隐秘。


2、用毛发做亲子鉴定,跟用血液做亲子鉴定准确率一致,在样本采样成功的情况下。


亲子鉴定的方法各异,但是其基本原理都是相同的,都是根据孟德尔遗传学定律,运用现代生物技术,对被鉴定者进行特定DNA片段的提取和检测,就通过比对鉴定者之间多个基因位点上的遗传信息,并对结果进行相应的计算和分析,得出鉴定结论的过程。



Hair sample collection method


First of all, we need to understand that hair samples are not like those seen on TV. They can be cut directly with scissors. It's not so. The real hair samples need to be pulled out directly and need hair follicles. So don't be cheated by TV programs. So how do we collect hair samples? Here is an introduction from our center


1. Have a clean tissue or envelope ready;


2. If the hair follicles are more than 5, pull out the hair follicles with the same method;


3. Wrap the hair with a prepared paper towel. Do not let the hair follicles and hair follicles touch together. If the hair is wet, wait for the air to dry before wrapping it with paper towel;


4. Write down the name and identity of the corresponding sample personnel, and then send it to the center by mail or directly to the center.


Benefits of hair samples:


1. It will not be limited by time, and the sampling method is relatively secret.


2. The accuracy rate of paternity test with hair is consistent with that of blood. If the sample is sampled successfully, the accuracy of paternity test is consistent with that of blood.


The methods of paternity testing are different, but their basic principles are the same. According to Mendel's law of genetics, modern biotechnology is used to extract and detect the specific DNA fragments of the examinees. By comparing the genetic information of multiple gene loci between appraisers, and calculating and analyzing the results, the identification conclusion is obtained.
