How many months can I do a paternity test?

Personal identification is a common type of identification and is needed by many friends in life. Paternity testing can be performed in the eighth week of pregnancy. Currently, the more popular identification methods include amniotic fluid and chorionic villus testing and venous blood testing of pregnant women. Before conducting a personal appraisal, you can first understand the process and methods of the appraisal, and choose a formal organization to conduct the appraisal.

At how many months of pregnancy can a paternity test be done?

Generally speaking, a paternity test can be done in the 8th week of pregnancy, which is about two months. However, there are two main popular methods of paternity testing. Which paternity test to choose depends on your needs.

What types of paternity tests are there?

1. Use amniotic fluid and chorionic villus for testing

This method may be risky for pregnant women because it requires surgery to obtain the sample for testing. So don't use this method unless necessary.

2. Take venous blood from pregnant women

This method has little effect on pregnant women and fetuses, and it also has a certain degree of accuracy, so if a paternity test is needed, this is a better method.

What is the accuracy rate of fetal paternity testing?

Whether it is conventional or non-invasive fetal paternity testing, their accuracy rates are the same. The accuracy rate for confirming the parent-child relationship is over 99.99%, and the accuracy rate for denying the parent-child relationship is close to 100%. Now, drawing amniocentesis for paternity testing is a mature technology. The key is that drawing amniocentesis has high requirements and can only be done in Grade 3A or above hospitals. It is based on Mendel's laws of inheritance. A child's genes come from both parents, with each providing half of the genes. So the child's genes can definitely be found in the gene fragments of the parents. If there is no match, then it can be proved that they are not biological children. Because a person's genes have been determined when the fertilized egg combines, no matter how it changes later, the genes will not be changed. The key to DNA paternity testing technology is to match the degree of similarity of genetic loci. So it’s the same no matter when you do it.
