DNA paternity testing is the best way to confirm a father / child biological relationship. A paternity test during the pregnancy is technically possible, but illegal. Right after the birth, a test can be conducted without risk for mother or child.
Once the pregnancy has been determined a paternity test could be conducted. However, in Germany such pre-natal tests are forbidden unless the pregnancy is the result of a serious crime. Please seek legal advice and/ or consult with your laywer or gynecologist
The taking of samples for a paternity test is a non-invasive process and not painful for the baby. The newborn can be sampled directly after the birth. This can be carried out in the hospital by a doctor or the midwife. Please do not take the samples directly after nursing the baby. The child’s oral mucosa may contain maternal cells. Please wait about 30 minutes before the sampling.
In case a pre-natal test is allowed to be conducted there are several possibilities to remove cell material:
1) At a very early stage during the pregnancy it is already possible to puncture the placenta to collect fetal cells. With those cells a paternity test can be conducted. This is an ivasive taking of samples. Complications may seldomly occur.
2) After the 13th week of pregnancy an amniocentesis is possible. This also is an invasive procedure. The Amniotic fluid contains fetal cells which can be used in a paternity test.
3) a non-invasive procedure to take fetal cells is through the maternal blood. The pregnant woman's blood is being processed to isolate the foetus' DNA. It can thus be used in a paternity test
Important – please note
** In Germany it is illegal to conduct a prenatal test. Exceptions are regulated by law
