What is the minimum probability that the DNA paternity test result is not biological

Samples that can be used include blood, blood stains, hair, amniotic fluid, sperm spots and mixed spots, saliva, cigarette butts, chewing gum, bones, muscles, etc.

Blood, oral mucosa, and hair are the three types of routine samples, and they are also the most used samples in DNA paternity testing. There is no direct relationship between the accuracy of paternity test and the sample, and the accuracy of DNA test is only related to the accuracy of the test. For example, if you use a kit with more detection sites, the results will be more accurate.

The North American Paternity Testing Center has the answers.

The composition of each family is closely linked because of the bloodline, the whole family lives together, if you encounter difficulties in life, we also have to face it together, but life is always twists and turns, in the process of time accumulation, our view of things will also change, from the initial youth to become more mature, in work and life, due to the different things in contact, each person's accumulated experience is also very different. So if the value of the paternity test does not reach 90%, it is still not biological? Let's take a closer look.

Happy families are mostly the same, unhappy families are varied, this sentence is not just written on paper, but in real life, it has been verified again and again. Many families have no choice but to take a paternity test, because they can't be sure whether their child is biological, based on blood relationship, so they can't help but do it, like eating a bite of a fly. So if the value of the paternity test does not reach 90%, it is not biological to a large extent, because the paternity test technology is now very mature and reached, then it is obvious that the father and son are indeed paternity by scientific identification.

This kind of bloody plot, we often see it in TV dramas, but life is often more exciting than TV dramas, if you want to do a paternity test, then to a large extent, the root cause, doing a paternity test is just a result. In fact, for biological and non-biological children, if the child has been raised for many years and has no blood relationship, he already has a deep affection.

The above is the content of the collation about whether the paternity test value does not reach 90%, whether it is biological or not. Based on the traditional concept, everyone still cares a lot about blood relations, including the patriarchal phenomenon in many regions, and the connection between people is not only blood, but also the friendship of getting along every day.

It does not have to be biological, and generally only when the value reaches can it be considered biological.

Concern. It is not necessarily biological, and Lixiang can generally only be recognized as biological only when the value is reached.

It is definitely not biological, and if it is biological, the result of the identification should be 99%.

The results of the paternity test are generally two, excluding the biological father relationship and not excluding the biological father relationship, that is, the elimination method is used, so sometimes it is impossible to determine whether it is biological or not. If the similarity is greater than that, it can be sure that it is biological, and if it is not the same as three or more gene loci, the parental relationship is excluded. Suppose you are identifying 20 loci, i.e., 2 loci are different, and this result may be due to two reasons:

First, genetic variation; Second, non-biological. In other words, the supervisory agency is right, your result, indeed, can only be a biological relationship that cannot be ruled out. But the possibility of biological birth is still very high.

In fact, I personally think that whether it is biological or not is not so important. As long as the child doesn't know the model, as long as the child is really with you now, then the child is biological, he has only one father, and it will be the same for the elderly in the future.

If you must want to know, you can also do it, find an authoritative point of agency, even if it is still the same institution, and identify it again, because the identification is a random locus, so the result may be different, but it is not excluded that the result is still the same. Because there will be genetic variations, even biological fathers and daughters may not be able to achieve such a high level of promotion.
