Once the samples are received, the laboratory begins the testing process by isolating the DNA from the mouth swabs. The pure DNA is then amplified using 16 different DNA primers. Those DNA primers will attach to different areas of each person’s DNA. The amplified DNA is then analyzed and "mapped out" according to where those DNA primers attached (loci). The loci are then analyzed and compared by our staff of PhD’s.

A child gets half of his DNA from his biological mother and half from his biological father. The child's two DNA loci are compared to the loci of both the mother and the alleged father. If the alleged father matches the child, then a paternity index can be calculated based on how common that loci is within a population (race). A paternity index is calculated for each loci and then multiplied together to give a combined paternity index. From there we are able to calculate a probability of paternity percentage. The probability of paternity must be 99.9% or higher in order to conclude that the alleged father is the biological father of the child. If the tested man does not match the child, the probability of paternity is 0% -- he cannot be the biological father of the child. In order to determine that the man is excluded as the biological father of the child, we must see at least three loci that do not match.
