First off, we need to present a couple of definitions and the scope of our guarantee. An INCLUSION takes place when a genetic marker between two tested people is the same. Since genetic information is passed from parents to children, an INCLUSION is seen as an indicator that the two people may be related. An EXCLUSION takes place when a genetic marker between two tested people is not the same. An exclusion is seen as an indicator that the two people may not be related. In paternity, if a man is the biological father of a child, we would expect markers at all 15 systems to match, and this is what happens in almost all paternity cases.
This guarantee assumes that the persons tested are each members of one of the following races: Asian-American, African-American, Caucasian-American, or Hispanic-American. While we can test families of any race, we have databases of genetic frequencies based on peoples of the aforementioned races, and so our math becomes more conservative and the possibility arises that the statistical probabilities will not be as high as they would be otherwise.
In the case that there are no exclusions and we've tested the mother, child, and alleged father, we guarantee that our Paternity Test will yield probabilities of greater than 99.999%. If those circumstances are met and we don't yield a probability greater than 99.999%, we'll refund 50% of the cost of the test.
