What are the procedures for paternity testing?

According to the different purposes of identification, paternity test can be divided into judicial identification and personal identification. Judicial appraisal refers to the appraisal that must be issued by relevant institutions and completed through a series of judicial notarization procedures. It has legal effect and can be used as court evidence. Personal identification is only a biological comparison of an individual's genetic genes. The identification process is relatively simple, but it cannot be used as court evidence.

If the purpose of paternity test is to know the results for yourself, and it is not necessary to use it for judicial purposes, you can provide samples of the identified person without providing documents, photos, etc. For the samples you provide, the appraisal center will generally accept the entrustment of paternity test. Be legally responsible for the accuracy of the appraisal.

If the purpose of paternity test is to be used as legal evidence in litigation or registered permanent residence, then you need to provide: the identification certificate of the appraiser (that is, ID card, household registration book, passport and other relevant documents that can prove your identity). It is also necessary to provide a power of attorney from the local police station or lawyer's court, and then under the supervision of the judicial appraisers of the appraisal center, all the appraisers will be present to collect samples. The judicial appraisal report issued by the appraisal center has legal effect throughout the country.

All nucleated human cells can be used for DNA identification.

The most commonly used samples are blood, blood stains, hair with hair follicles, oral mucosal cells (oral swab) and so on. Other samples such as fluid products (fetal sac tissues or villi), toothbrushes, fine spots, mixed spots, muscles, teeth, bones, cigarette butts, nails, worn underwear and socks, used paper cups and even fetal amniotic fluid can be used.

1. If you sample yourself or your child (the child is under 5 years old), it is recommended to choose a non-invasive oral swab as the test sample first;

2. If you want to identify the fetus, please go to the hospital to take amniotic fluid as a sample after 16 weeks of pregnancy.

In recent years, many domestic paternity testing institutions have mushroomed, and the accuracy of technology and results is uneven. The so-called appraisal institutions, a large part of which are biological preparation companies or individuals, use old instruments and equipment or some teaching equipment that has not been approved by the state to obtain experimental results through their own operational knowledge. This kind of appraisal operation standard is low, the experimental environment is poor, the accuracy of appraisal results is relatively low, and it has no judicial effect.

For this kind of appraisal service, we must not blindly choose an appraisal institution, because formal paternity testing requires very expensive instruments and strict technical operation, so as to ensure the authenticity and accuracy of the results, while general hospitals and biological companies cannot and do not have the qualification to be DNA paternity, so we sincerely warn you that if you want to do paternity testing, you must go to a formal paternity testing institution, so as to ensure the authenticity and accuracy of the results.
