I believe most friends are aware of the medical method of paternity testing, and with the rapid improvement of medical technology, fetal paternity testing can be conducted before the baby is born. And the paternity test of the fetus is very safe and effective, and it will not cause harm to the pregnant mother and the baby's body. So how long can fetal paternity testing be done?
Under normal circumstances, fetal paternity testing can be conducted around twelve weeks of gestation. At this stage of pregnancy, the gestational age is relatively small, and fetal villi are usually taken for identification. If the fetus is 16 weeks old, amniocentesis DNA can be performed, mainly by collecting samples from both parents and the amniotic fluid of the pregnant woman.
In addition to the two testing methods mentioned above, paternity testing can also be conducted through minimally invasive examination of fetal chromosomes from the mother's blood. However, the accuracy of this method is slightly lower compared to the above two methods.
It is recommended that all friends go to regular tertiary hospitals for paternity testing, so as to ensure the safety, accuracy, and effectiveness of paternity testing. At the same time, it is important to prepare all the necessary materials and certificates for paternity testing. Please also believe in this mature medical method of paternity testing. If the child is biological, the same genetic fragments as the parents can definitely be found in the child's genes.
