How Does a Paternity Test Work?

A paternity test is based on the principals of DNA. Genetic paternity testing identifies the unique genetic profile of an individual. A child gets one half of his/her genetic makeup from the mother and the other half from the biological father.

By comparing the child’s genetic profile with that of the alleged father, a Paternity Test determines whether this person is the real biological father.

In the laboratory, DNA is extracted from the samples sent to the lab. The DNA samples are compared side-by-side. The lab looks for matches. If the man tested is the biological father of the tested child, his probability of paternity will be 99% or higher.
