How many days does the paternity test usually come out?

Many people are doing paternity testing for the first time, and they don't know much about the process of paternity testing and the time required to produce the results. These are all issues that people are concerned about, because the time required by each organization is different, but in general, the difference in days will not be too much. So how many days does the paternity test usually produce results?

How many days does the paternity test usually come out? First of all, not all appraisal institutions can do paternity testing, and only some appraisal institutions have such business. It is recommended to contact the appraisal institution first. Secondly, paternity testing generally requires the presence of both parties. The time of paternity test varies with different appraisal institutions. As far as practical experience is concerned, some need a week or two, while others need a month or two. You can directly contact the appraisal agency for consultation.

Paternity identification is the main part of forensic material evidence identification, which uses the theories and techniques of forensic medicine, biology and genetics to analyze genetic characteristics and judge whether the relationship between parents and children is biological, starting from the similar characteristics of morphological structure and physiological function between offspring and parents. Simply put, it is to identify the genetic relationship between parents and children through blood type or DNA testing, such as parents' blood, hair, saliva, oral cells and bones.

The time required for judicial paternity test results varies from institution to institution, and generally takes ten working days. For example, the judicial paternity test report issued by the Judicial Appraisal Center of the First Hospital of Jida University is within ten working days.

There are many people targeted by judicial paternity test, mainly including: children who have lost their birth certificates, people with immigration needs, students who need to go to school but have no hukou, and other people who need to settle down. Judicial paternity test generally requires appraisers and authenticatees to collect on-site images and samples from judicial authentication institutions. Every link of the whole process needs to conform to the judicial procedure, and the information should be uploaded to the center of the national judicial system, so the report has legal effect.

Paternity test There are two ways to do paternity test, one is invasive paternity test and the other is non-invasive paternity test. Invasive paternity test refers to the extraction of amniotic fluid in the second trimester to obtain the DNA information of the fetus in amniotic fluid, and then amplify the DNA information, and then compare it with other people's medical records to determine the genetic relationship. Amniocentesis is called invasive paternity test because it has certain risks and is easy to cause complications such as abortion and infection. Non-invasive paternity test is a test method to extract maternal peripheral blood, extract fetal DNA information from maternal peripheral blood, and then amplify the DNA information to determine the genetic relationship. Because only the peripheral blood of pregnant women is taken, there is no risk, so it is called noninvasive paternity test.

Paternity DNA paternity can take samples from any tissue, such as oral epithelial cells. Traditional paternity testing requires blood type testing: the child must be at least 6 months old and need a lot of blood samples. The process is complicated, the sampling is painful and the error rate is high. DNA paternity is very different. Even before the child is born, there is no mother's participation, and it is the most accurate one in the parent-child test at present-the accuracy rate can reach 99.99999%, so it has the characteristics of exquisiteness, simplicity, rapidity, economy and practicality. At present, the charging standard for paternity testing in DNA testing laboratory is 3,600 yuan for a case with less than 3 people, and the results can be obtained in two weeks. If there are special needs, the conclusion can be drawn in three days. Traditional blood type judgment has its role to some extent, but paternity test can not be based on blood type.
