What does paternity test need? What hospitals can do?

Use the theories and techniques of medicine, biology and genetics to judge whether there is a biological relationship between parents and children in dispute. Paternity test is also called paternity test and paternity test.

Paternity identification is an important content of forensic living identification, which mainly displays in:

1。 Family disputes, or pregnancy before marriage, doubt that the child is not biological.

2。 It is suspected that the delivery room or nursery of the hospital is wrong for the newborn baby.

3。 Long-lost family, acquaintances.

4。 Immigration notarization needs to determine whether immigrants are related to someone.

5。 When it comes to the family planning policy, I suspect that my child has been adopted or my super-born child has been raised by others.

6。 Inheritance disputes should determine the biological relationship or the determination of the biological father of IVF.

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. DNA paternity can take samples from any tissue, such as oral epithelial cells. 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.

At present, DNA paternity uses the repeated base sequence (STR) in human genome and PCR technology to identify individuals.

STR, as the second generation molecular marker, will inevitably be replaced by the third generation molecular marker technology, which was born in the late 1990s: a technology called single nucleotide polymorphism (SNP). The identification of the bodies burned by fire and high temperature in the 9 1 1 terrorist attack in the United States was once slow due to the restriction of STR. However, the final identification work was successfully completed, thanks to the creative decision of scientists using SNP technology.

At the same time, scientists of China paternity testing information network are developing SNP detection technology for paternity testing, aiming at overcoming the technical difficulties of combining SNP technology with gene chip, completing the design and manufacture of gene chip for paternity testing, and taking the lead in applying it to paternity testing in China.

1. What is a personal confidential paternity test?

Personal confidential paternity test is a DNA paternity conducted by collecting identification samples without taking judicial sampling procedure under the condition of fully respecting the privacy of appraisers. This kind of appraisal, without showing any documents of the client or even providing his real name, can collect the appraisal materials by himself and entrust the appraisal. Because of the secret way, simple steps and low cost, it can provide decision-making reference for whether judicial expertise is needed. Most people do paternity tests just to know if the child is their own, and they don't want to take this matter to court. In paternity testing in Europe and America, the number of personal identification far exceeds that of judicial identification.

2. How to do a good job in personal confidentiality appraisal

The client can get the results by mailing samples without providing any certificates or photos. Personal appraisal has strong confidentiality, which is suitable for those parties who only want to know the appraisal results, but the appraisal institution is only responsible for the samples submitted for inspection and is legally responsible for the appraisal results.

3. What is judicial paternity test?

Judicial paternity test is an activity that uses professional knowledge and technology, collects identification samples according to legal procedures, and conducts identification and judgment. Judicial paternity test has judicial effect and can be directly used as court evidence. The sampling procedure is strict, and all materials provided must be true and reliable.

4. How to do judicial paternity test?

You need to prepare corresponding documents (ID card, passport, military officer's card or child's birth certificate, etc.). ) and a copy. 65438+ 0-inch or 2-inch bareheaded photos of the same floor. Fill in the power of attorney and appraisal application form, and collect the fingerprint of the appraiser.

5. The badge stamped on the judicial appraisal report?

, official seal of Ma and ilac-MRA technical seal. Only the judicial expertise report issued by an institution recognized by the Ministry of Justice can be used in national courts, and the judicial expertise report of an internationally certified appraisal institution can be used internationally.
