What is DNA Paternity Testing?
3. DNA paternity testing examines the genetic composition of a child which is inherited from its biological parents. DNA is located throughout the human body and in an identical form throughout the human body. A child inherits there DNA from both the biological mother and father. DNA can be found in the blood, cheek lining, bone, teeth, semen, saliva and muscle. During the paternity testing process, the genetic characteristics of the child are compared to those of its mother and the remaining genetic composition that is not found in the mother, has been inherited from the biological father. If the tested man ( alleged father) does not share the same genetic traits as the biological father of the child, he is excluded 100%. If the tested man ( alleged father) shares the same genetic composition, then the probability that this man is the true biological father is calculated and reported as a % of probability (usually 99.99%).
With the exception of identical twins, every person has very unique geneticcode identified by DNA (deoxyribonucleic Acid) found in each cell in the body. Based on the fact that we inherit half of our DNA from our father and half from our mother, DNA samples are tested to disprove or prove the relationship between a child and an alleged father. The child’s genetic profile is then compared to the profiles of the mother and alleged father. A statistical analysis is performed to calculate the probability of paternity.

A DNA paternity test compares a childs DNA pattern with that of the alleged father to prove or disprove their relationship with each other. We apply Polymerase Chain Reaction (PCR) V based analysis of Short Tandem Repeats (STR) of DNA fragments. By comparing the sizes of different STR loci, a unique genetic profile is produced for each tested individual. The childs profile is compared with the profile of the mother and alleged father to confirm that he or she has inherited DNA from the alleged father. We then perform statistical analysis to calculate the Paternity Index, which determines the probability of paternity. We routinely analyze 16 STR loci, which include, and exceed the 13 loci used by the FBI.
