DNA Paternity Testing

A paternity test helps determine whether the adult being tested is the biological father of the child or children. A standard paternity test also includes obtaining a DNA sample from the mother, if available. Testing the mother’s DNA is best because it allows us to report a higher probability of paternity (≥99.95%). Although the mother’s participation is recommended, a paternity test may also be conclusive without testing a DNA sample from the mother.

TheDNALab provides home tests as well as court-approved legal tests. Find out which one you need now.

Standard DNA samples are collected by gently rubbing a soft sponge on the inside of your cheek. The process is non-invasive, quick and gentle enough for newborns.
For a regular paternity test, separate samples must be compared for each child and the alleged father(s).

The science:

A paternity test compares the DNA of the alleged father and child/children to determine if their DNA matches at 50% (children inherit 50% of their DNA from each parent).

If the DNA from the alleged father does not match the DNA from the child, the alleged father is excluded as the biological father, reporting a 0% probability of paternity.

When the DNA does match, then the alleged father is concluded to be the biological father of the child, typically at a minimum probability of paternity of 99.95% or higher.
