Can a paternity test be done on a pregnant child?

There are a lot of things to do during pregnancy. In addition to ensuring that you can maintain a happy mood, a regular life, and a comprehensive diet, you also need to add a lot of nutrients during pregnancy for your body and the baby in your belly. Most people know that they need to take ultrasounds when they are pregnant, so many people will immediately ask, can paternity testing be done during pregnancy?

Can paternity testing be done during pregnancy?

DNA testing can be done before the fetus is born. After a period of pregnancy, the sperm and egg combine to develop into test tube embryo tissue with DNA information. Moreover, the test tube embryo tissue will exchange certain substances with the amniotic fluid of the pregnant woman bathing therein. Therefore, the amniotic fluid of pregnant women contains a large number of fallen cells of embryonic tissue, which contain the DNA information of the fetus. Therefore, prenatal DNA testing of pregnant women can use amniocentesis to collect amniotic fluid of pregnant women to obtain fetal DNA and compare it with the DNA of the unidentified father to achieve the purpose of DNA testing. Moreover, the test results of this evaluation method are consistent with the evaluation results after the fetus is born. Depending on the stage of pregnancy, the fetus's DNA sample can be obtained through amniocentesis.

The following report mainly shows the operation process, sample types and sampling opportunities of this method.

Sampling time: within 16-24 weeks of pregnancy. Sample type: fetal cell sampling from amniotic fluid of pregnant women. Sampling procedure: sampling time is determined by routine physical examination. The obstetrician and gynecologist uses B-ultrasound to obtain the amniotic fluid of pregnant women with a hollow needle. The samples required for prenatal DNA testing are: fetal sample (amniotic fluid of pregnant women), mother's DNA sample, and if the father's DNA sample is genetically modified, we would like to remind customers that amniocentesis has certain risks to the fetus. This type of examination must be carried out with the consent and participation of the pregnant woman, and must be carried out under the guidance of a gynecologist in a regular hospital. It is best to be carried out in addition to other gynecological amniocentesis. Also, please remember to contact our sales representative in advance before conducting amniocentesis to ensure that all your inspection steps are safe and smooth.

1. FAQ: If the pregnancy is more than 7 weeks, B-ultrasound confirms that the length of the embryo has reached 10mm, and the embryo and initial heartbeat can be seen. After maternal blood screening, if it is a boy, a minimally invasive DNA test before delivery in Hong Kong can be done.

2. Have given birth to a boy within six months, or had an induced abortion or miscarriage within three months (because the gender of the fetus must be determined first when doing minimally invasive DNA testing before delivery in Hong Kong, because the baby's mineral DNA will enter the mother's blood, so there will be errors in the gender test of the fetus)

3. Those who have undergone transplantation, blood tests, intravenous injections, etc. within one year are not allowed to have the test (transplantation, blood tests, intravenous injections may carry Y chromosome genes, which will make the fetal gender test inaccurate)
