DNA is passed down from parents to children and can be found throughout the body. Common samples of DNA are blood, bone and skin cells. For testing purposes, they are typically taken from inside the mouth. Heres how Paternity Testing Corporation (PTC) conducts a DNA test:

Step 1

Clients are finger-printed, photographed and their mouths are swabbed. The samples are sent to a lab in the US for processing.

Step 2

A paternity test works by identifying certain specific size pieces of DNA that the child received from his or her biological father. If the man has the same size pieces as the child, he is likely to be the biological father.

Unrelated individuals are unlikely to have the same specific size pieces. PTC guarantees that its normal DNA paternity tests have an accuracy of higher than 99.99 per cent.

Step 3

Once samples reach the lab, results are ready within two business days. But clients typically wait 10 days due to shipping and the number of cases that have to be handled.
