A paternity test compares the DNA profile of the two individuals. A child's DNA is inherited from the mother and the father, and a comparison of the DNA of the child with that of the alleged father can determine whether that person is the biological father or not. We supply a DNA testing kit along with instructions on how to use it (our DNA Sample Collection Guide). The guide is included with the kit, and is also published on our website. Once the samples have been returned to our laboratory, the tests are carried out and results sent back to you.
