Is it possible for parents and children to do dna testing?

Can paternity test be conducted without the participation of the biological mother?

The biological mother can choose not to participate in the appraisal. In paternity testing, the samples of the child and the presumed father are usually enough to know the result, and the mother can choose not to participate in the test. The birth mother has also been tested, and the conclusion is more accurate. Because a child's genes come from his mother and one from his father. If there is a biological mother as a reference (that is, parental identification), the gene of the biological father can be clearly deduced according to the genotype of the mother and the child, and then compared with the controversial father (that is, you). If there is no mother, the gene of the biological father is directly deduced from the gene of the child. There are many possible situations, and the numerical deviation obtained by statistics is relatively large.

In fact, the detection results of our commonly used 15 STR loci are all simulated by computer. Two unrelated people, with this detection system, at least three have violated the genetic law, and 99.99% non-fathers can be excluded, but11000 may not be excluded or misjudged. So the difference between us and other institutions is that we have added a kit and nine detection indicators, which are more accurate and avoid deviations as much as possible. This is also the reason why the single parent appraisal fee is higher than that of the biological mother.

Do I need to take part in the paternity test?

Paternity identification can be divided into two types, one of which needs judicial effect, such as litigation, immigration, household registration and so on. The other is just knowing the result, which does not involve judicial application. For the former, just provide the customer's identity information. Parents provide identity cards, and children can provide birth certificates or household registration books to prove their identity (proving that the parties concerned are the children's guardians). Those who have entered the judicial process or have hired a lawyer may entrust a judge or lawyer to make an appraisal. It can also be entrusted by both parties. For the second type, you don't need to provide any information, you can be anonymous, and you can bring your own samples. The two charging methods, appraisal methods and appraisal standards are exactly the same, only the procedural differences, that is, a legally effective judicial appraisal book, which requires us to review the identity cards of the parties and take photos.
