Prenatal Paternity Test: Ensuring Certainty Before Birth

The journey to parenthood is marked by excitement, anticipation, and sometimes, uncertainty. In today's advancing technological landscape, couples are presented with novel solutions to ease their doubts and concerns. One such solution is the non-invasive prenatal paternity test, offered by DNAForce, which allows individuals to determine the biological father of their unborn child as early as the 7th week of pregnancy. This groundbreaking procedure boasts an accuracy rate of 99.9% or higher, offering expectant parents an unprecedented level of assurance.

The Science Behind Prenatal Paternity Testing

DNAForce has pioneered a revolutionary method that relies on advanced genetic analysis. By comparing genetic markers present in a blood sample from the mother with those from the alleged father's DNA, scientists can establish paternity with exceptional precision. Unlike traditional methods that necessitate invasive procedures like amniocentesis and chorionic villus sampling (CVS), the non-invasive prenatal paternity test eliminates the risks associated with these older methods. These invasive techniques carry the potential danger of fetal loss and are often not authorized for paternity determination in certain regions, such as most provinces in Canada except Quebec.

Innovative Technique: Minimizing Risk, Maximizing Accuracy

The breakthrough technology hinges on the discovery that the mother's blood contains sufficient fetal DNA for accurate testing. The use of a powerful centrifuge enables the separation of fetal DNA from the mother's blood, making the invasive surgical procedures obsolete. With a focus on safety, convenience, and accuracy, this approach alleviates the need for an obstetrician-gynecologist (OB-GYN) to perform the test, as any healthcare professional, such as doctors, nurses, or technicians, can collect the blood samples. The test examines up to 300,000 genetic markers to establish paternity, and the results are typically available within approximately 8 business days following sample receipt by the laboratory.

Navigating Potential Hurdles

While the prenatal paternity test is designed to be straightforward and non-invasive, there are rare instances when initial attempts yield insufficient DNA. It's crucial to understand that this occurrence isn't indicative of any issue with the unborn child. The level of fetal DNA in the mother's blood fluctuates throughout the day. If a sample yields inadequate DNA, the laboratory provides additional recollections free of charge. Notably, at the 7th week of pregnancy, only 10% of mothers require recollection. As the pregnancy progresses, the likelihood of needing recollection decreases significantly, offering reassurance to concerned parents.

More advanced methods now make it possible to do a prenatal paternity test using blood from the mother.

Interpreting the Results

DNAForce ensures that the results of the prenatal paternity test are clear and easy to comprehend. The outcomes are presented as a simple "yes" or "no." Expert staff members are available to address any questions or concerns. If the alleged father is not the biological father, the results indicate a 0% likelihood, known as paternity exclusion. Conversely, if the alleged father is the biological father, the results reflect a probability of 99.9% or higher, referred to as paternity inclusion.


The non-invasive prenatal paternity test offered by DNAForce brings newfound clarity and certainty to expectant parents. By combining cutting-edge genetic analysis with non-invasive techniques, this procedure presents a safe, accurate, and convenient way to determine paternity as early as the 7th week of pregnancy. With minimal risk, a high accuracy rate, and expert support, the prenatal paternity test offers a vital tool for couples navigating the complexities of pregnancy and parenthood.
