做亲子鉴定需要哪些

在办理亲子鉴定的时候可以采集的样本的类型是比较多的,可以根据自己的资金来采集,也可以根据自己的方便去采集,本中心比较推荐的还是血痕和血液作为样本,这两个类型的样本包含的DNA是比较多的,采集也相对方便,比较容易提取;另外一个就是口腔拭子;

一、采集口腔拭子的方法

准备工作:

如果孩子在2岁以下不建议,首先让孩子用干净的水去清洁好口腔,如果孩子比较小,可以让其先喝点清水。

采样步骤:

(1)如果有医用棉签就用医用棉签,如果没有家用棉签也是可以的,准备好5根左右,然后准备好干净的纸巾,和信封;

(2)可以到本中心采集,也可以自己采集,用棉签在口腔内额旋转,搅拌3-5圈拿出,重复5根;

(3)等待风干后用干净的纸巾包住即可,然后直接拿到本中心,或者邮寄等方式,记录好自己的样本和孩子的样本以免搞混;

华泽基因DNA亲子鉴定中心,特别提示:除了血痕和血液,就是口腔拭子比较好采集了,口腔拭子需要静待风干,不能用风筒去吹,需要自然风干,不然可能会造成口腔拭子无法提取到DNA;

二、血液样本采集方法

准备工作:

建议到正规的医院去委托专业护士采集,装血液用的医用试管是有加抗凝剂的或是EDTA抗凝管,体积可装10ML血液,抽完后及时送到鉴定中心,如果天气热的时候,需要放到保温瓶后加冰,冷冻送达;

采样步骤:

①、首先,消毒,用专用医院采血试管抽取10ML,然后上下摇晃试管让抗凝剂和血液混合,然后写上样本标识,如:父、母、子等;

②、为了防止试管损害,请尽快送达检验中心,采集好的血液可保存时间是相对比较长的,但是还是需要避免试管损坏,如有损坏,则需重新采样;

华泽基因DNA亲子鉴定中心,特别提示:如果不方便自己采样,可以直接到本中心采,或者到三甲医院找到专业的采样人员帮忙采集,如果是邮寄可以加冰块冷冻邮寄,这样就不会因为天气原因,而造成血样变质;采血器械应该是一次性医用注射器,必须干净清洁,如果不是医护人员,不建议自己采集;

三、血痕样本采集方法

血痕是DNA亲子鉴定最常用的方法。

准备工作:

清洁好双手,带好医用手套,准备好,一次性采血针,和采血卡,采样信封;

采样步骤:

1、一般情况下,做司法鉴定都是要求血痕样本,采集快捷,方便,直接到本中心采集即可;

2、先帮采样人手指消毒,然后用采血针轻轻扎穿手指,让其自然出血如果没见出血,可亲亲按压手指四周;

3、用准备的采血卡,才手指上采集3-5滴血;写好相关采血人信息;

4、放进信封中保存送达鉴定中心,因为是干的血液,所以保存时间相对比较长哦;

华泽基因DNA亲子鉴定中心,特别提示:血痕采集相对采集速度比较快,简单快捷,比较推荐,人体身上任何部位都可以采集,血痕自然干,不可借用外力风干,不同人的血液不可掺杂在一起,以免相互污染,血痕不可用密封袋装,不然里面产生了水蒸气会让血痕发霉,影响检测结果;


What does paternity test need

There are many types of samples that can be collected in the process of paternity testing. They can be collected according to their own funds or according to their own convenience. Blood stains and blood samples are recommended by our center as samples. The two types of samples contain more DNA, and collection is relatively convenient and easy to extract; the other is oral swab ;

1、 Methods: oral swabs were collected

preparation:

If the child under 2 years old does not recommend, first let the child with clean water to clean the mouth, if the child is relatively small, you can let him drink some water first.

Sampling steps:

(3) After air drying, wrap it with a clean paper towel, and then take it directly to the center, or mail it. Record your own samples and children's samples to avoid confusion;

Huaze gene DNA paternity testing center, especially points out: in addition to blood stains and blood, oral swabs are better to collect. Oral swabs need to wait for air drying, and can't be blown with an air duct. They need to be dried naturally, otherwise, oral swabs may not be able to extract DNA;

2、 Blood sample collection method:

preparation:

It is suggested to entrust professional nurses to collect blood in a regular hospital. The medical test tube for blood is provided with anticoagulant or EDTA anticoagulant tube. The volume can hold 10ml of blood. After pumping, it should be sent to the identification center in time. If the weather is hot, it needs to be put into the thermos bottle and then iced and delivered to the hospital;

Sampling steps:

① First of all, disinfect, take 10ml from the special hospital blood collection tube, then shake the test tube up and down to mix the anticoagulant and blood, and then write the sample identification, such as: father, mother, son, etc;

② In order to prevent damage to the test tube, please send it to the test center as soon as possible. The collected blood can be stored for a relatively long time, but it is still necessary to avoid damage to the test tube. If there is damage, re sampling is required;

Huaze genetic DNA paternity testing center, special tips: if it is not convenient to sample yourself, you can go to the center directly or find professional sampling personnel to help collect. If it is mail, you can add ice to freeze mail, so that blood samples will not deteriorate due to weather. Blood collection equipment should be disposable medical syringes, which must be clean and clean, If it is not a medical staff, it is not recommended to collect them by themselves;

3、 Blood sample collection method:

Bloodstain is the most commonly used method for DNA paternity testing.

preparation:

Clean hands, wear medical gloves, ready, disposable blood collection needle, blood collection card, sampling envelope;

Sampling steps:

1. In general, the forensic identification requires blood samples, which are fast and convenient, and can be collected directly to the center;

2. First, disinfect the finger of the sampling person, and then gently prick the finger with a blood sampling needle to let it bleed naturally. If there is no bleeding, you can press the finger around personally;

3. 3-5 drops of blood were collected on the finger with the prepared blood collection card, and the relevant information of the blood collector was written;

4. Put it in the envelope and save it to the identification center. Because it is dry blood, the storage time is relatively long;

Huaze gene DNA paternity testing center, special tips: bloodstain collection speed is relatively fast, simple and fast, more recommended, any part of the human body can be collected, blood stains natural dry, can not borrow external air drying, different people's blood can not be mixed together, in order to avoid mutual pollution, blood stains can not be sealed bags, otherwise water vapor inside will make blood stains Mold, affecting the test results;
