What is Paternity DNA Testing?

The Paternity DNA Test will determine if a man is the biological father of a child. Because DNA is shared equally between mother and father, we are able to determine, with a set calculation, whether the man IS or IS NOT the father.

Science of Paternity

Knowing how individual DNA strands transfer over multiple generations allows us to successfully determine genetic relationships. See Science of Paternity for more information.

Statistics of Paternity

When discussing the DNA results, we'll provide a probability whether two participants are related. Depending on the characteristics of the provided sample and complexity of the case, the results will be 99.9999% accurate. To read more about probability and accuracy, visit Statistics of Paternity.

Paternity DNA Test Details

Participants This test requires the Alleged Father and Child. Including the mother is optional, but recommended.
