Amniocentesis for paternity testing, is it possible?

With the development of modern medical technology, it can be said that medical care is becoming more and more advanced. In the past, when doing paternity testing, it was necessary to collect blood, but now there are many methods that can achieve this effect. Amniocentesis is one of them. However, many people still express doubts about this. So the following will introduce you to amniocentesis for paternity testing. What are the results?

Amniocentesis is a prenatal diagnostic method in which a very small amount of amniotic fluid is collected and analyzed after puncturing the amniotic cavity. It is usually used as an auxiliary examination for Down syndrome screening and the determination of certain genetic diseases. During the 17th to 21st week of pregnancy, the living cells in the amniotic fluid reach 30%. At this time, it is most suitable to use a puncture needle to pierce the abdominal wall of the expectant mother into the uterine cavity, aspirate about 20ml of amniotic fluid sample, and then obtain the chromosome karyotype through 7-14 days of amniotic fluid culture. After observation and analysis, whether the chromosomes will be deformed, the risk value of whether the fetus is a Down syndrome baby can be determined.

Can paternity testing be done through amniocentesis? Depending on the purpose of the identification, paternity testing can be divided into judicial identification and personal identification.

Judicial appraisal refers to an appraisal that must be completed through a series of judicial notarization procedures and with a letter of authorization issued by a relevant institution. It has legal effect and can be used as evidence in court. 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.

Paternity testing does not necessarily require the use of blood. Appropriate samples can also be obtained by oral swab, and the accuracy is the same. Since DNA exists in every cell in the body, the accuracy of the test results obtained from samples collected using the oral swab method is the same as that of blood samples.

The DNA paternity test will produce results in 1-5 days. Acceptable test sample types include: hair, blood, semen, toothbrushes, cigarette butts, oral swabs, etc. In most cases, worn, unwashed underwear can also produce good analysis results.

The purpose of paternity testing is to obtain accurate, reliable and legally effective test results. Therefore, we solemnly remind you to choose a regular national institution to do paternity testing. After all, you may only face such a thing once in your life, so please handle it with caution.
