Non-Invasive Prenatal Paternity

Non-invasive prenatal paternity testing (NIPPT) is a method used to determine paternity before the birth of a child without invasive procedures such as amniocentesis or chorionic villus sampling (CVS).

Here's how the process typically works:

1. Sample Collection: A blood sample is collected from the pregnant woman, usually through a standard blood draw. This sample contains a mixture of DNA from both the mother and the developing fetus.
2. Isolation of cff DNA: Specialized laboratory techniques are used to isolate the cell-free fetal DNA from the mother's blood sample. This involves separating the fetal DNA fragments from the maternal DNA.
3. Analysis of DNA: Once the fetal DNA is isolated, it is analyzed to determine the genetic markers or variations that are specific to the potential father(s). This is usually done through a process such as polymerase chain reaction (PCR) or next-generation sequencing (NGS).
4. Comparison and Interpretation: The genetic profile of the potential father(s) is compared with the fetal DNA to identify matches or exclusions. By comparing specific genetic markers, the paternity of the unborn child can be determined with a high degree of accuracy.

It's important to note that non-invasive prenatal paternity testing is typically performed for informational purposes and is not legally binding in most jurisdictions. However, the results can provide valuable insights into paternity before the child is born, allowing parents to prepare accordingly. Some key benefits of non-invasive prenatal paternity testing include:

• Safety: Unlike invasive prenatal testing methods, NIPPT does not pose any risk to the mother or fetus since it only requires a blood sample from the mother.
• Early Detection: NIPPT can determine paternity as early as 7-9 weeks into the pregnancy, providing parents with early peace of mind and allowing them to plan accordingly.
• Accuracy: When performed by our laboratory using validated methods, NIPPT can provide highly accurate results, often exceeding 99% accuracy.
