Prenatal DNA paternity Test
DNA prenatal paternity test determines whether an alleged man is the biological father of an unborn child. During pregnancy, the mothers’ bloodstream contains a mix of DNA that comes from her cells and cells from the placenta that matches the fetus DNA. The fetal DNA which is found in the expectant mother’s plasma is compared to that of the alleged father to check for proof that the man is or is not responsible for the pregnancy. The test is performed after 7 weeks of pregnancy. There are two types of prenatal paternity test namely:
- The Non-invasive prenatal paternity test (NIPPT)
- The invasive prenatal paternity test
The test samples needed for NIPPT are blood from the mother and a cheek swab from the alleged father. The invasive test requires amniotic fluid sample from the mother to drawn using amniocentesis.
If the man tested is determined not to be the biological father, then the report shows a 0% probability of paternity. If the man tested is considered to be the biological father, the report shows a 99.99% probability of paternity. Prenatal DNA Paternity testing can be used for legal or peace of mind purposes
