How long does it take to do a DNA test after pregnancy?

Many people are afraid that their wives will cheat on them. They raise their children and then the biological father of the child comes to take the child away. As a result, the child goes with the biological father and not the adoptive father. This really makes people want to vomit blood, it is particularly heartbreaking. How long after pregnancy can I do a DNA test?

Can I fly when I am pregnant?

Paternity testing generally requires samples from the mother and the suspected father, as well as samples of the fetus's amniotic fluid. If any one of the three is missing, it will not work. The fetal sample is sometimes mixed with the mother's, and the doctor must pay attention to distinguish them. The suspected father can choose hair, blood, saliva, semen stains, etc. as samples for testing. We often see TV dramas where two people recognize each other by dropping their blood into water separately to see if they mix. But this is actually not scientific and the result can easily be the opposite.

The first method is to collect the fetal amniotic fluid and chorionic villus as test samples. This is a more traditional surgical sampling method. Although it can accurately detect DNA, it is a surgical sampling method, so there are certain risks. The collection of fetal chorionic villus samples for testing should be carried out between 8 and 13 weeks of pregnancy, and the collection of amniotic fluid should be carried out between 14 and 28 weeks of pregnancy.

The second method is to directly collect venous blood from pregnant women as test samples, which is non-invasive fetal paternity testing. This method is non-traumatic and harmless to both pregnant women and fetuses. It can ensure the safety of mother and child and the accuracy of the test results. Generally, it can be done after 8 weeks of pregnancy until the baby is born.

In contrast, after 14 weeks of pregnancy, the fetal development gradually enters a stable period, and extracting a small amount of amniotic fluid will not affect its normal growth and development. Therefore, it has little impact on the fetus and the mother, and is relatively safe and reliable. Taking into account the individual differences of pregnant women and fetuses, the final decision on whether to collect chorionic villus or amniotic fluid will be informed by the clinician to the client. Fetal paternity testing is safe, and there is no need to worry too much about extracting amniotic fluid because this technology is now very mature.

The benefits of paternity testing

In fact, paternity testing is not like the paternity testing shown in those soap operas, because that kind of paternity testing is fake and has no scientific basis. Today I will talk to you about serious paternity testing, which is a paternity testing with scientific basis. Because in real life, some fathers and sons look very similar, and outsiders can tell at first glance that they are biological children. They also often say: The father and sons are simply carved from the same mold. However, there are some fathers and sons who look nothing like each other. Not only that, their personalities are also completely different. But this does not mean that the father and son are not biological children.
