Paternity Test Results: Genetic Organisation Table

DDC's laboratory tests at least xx different locations on your Dna, as listed in the "locus" column, and compares them with the same locations on the other tested parties. Each child inherits one re-create of this DNA segment from the mother, and i re-create from the begetter. These DNA segments are called "alleles". Our proprietary technology determines the length of each participant's alleles and compares them with the lengths of the alleged begetter's alleles to determine the number of matches. If the female parent participates, the mother's alleles will also be compared. In the case below, the child shown has two sets of alleles at each location tested, and you can meet that at least ane of these matches with the alleged father's alleles.

Note: Colored markings are for illustrative purposes only and are not included on actual reports.
Using statistics, the Paternity Index (listed as PI in the table in the upper left) indicates the strength of the match at each Locus (Deoxyribonucleic acid location). In most cases, at least one of the child's alleles at each location must match one of the father'south at that location. In improver, the DNA location that shows a participant'south sex (male or female), called the Amelogenin locus, is besides tested. This is listed at the bottom of the table. One X ways female, while i X and one Y ways male. Sometimes additional locations on your Dna must exist tested to strengthen the results – for example, when ii possible fathers are relatives. In this case, those are likewise listed. When a child has ii alleles that are the same size, it will testify as just one number on the table. For example, in the kickoff locus in this case, the kid received a "16" from both parents.

Paternity Exam Results: Combined Paternity Index

The Combined Paternity Alphabetize is the number on the lower left side of the report (in the Interpretation section), directly under the Genetic System Tabular array. If you are considered the biological father, in that location is a number listed for the Combined Paternity Index. If you are not considered the biological father, the written report shows "0." The Combined Paternity Alphabetize is an odds ratio indicating how many times more likely it is that the possible begetter is the biological father than a randomly-selected unrelated man with a similar racial background. In the case shown higher up, this homo is 533,475 times more than likely to exist the biological begetter. This number varies on a case by case ground. The higher this number, the stronger the results.

Paternity Test Results: Test Conclusions

The report also shows one of 2 conclusions: "is not excluded as the biological father" or "is excluded equally the biological father."

• If the determination states, " is not excluded as the biological begetter," this ways the possible father most likely IS the biological begetter of the child, since all data gathered from the exam supports a relationship of paternity.
• If the decision states, " is excluded every bit the biological male parent," this ways the possible father IS NOT the biological father of the child, since all data gathered from the test practise non back up a relationship of paternity.

Frequently Asked Questions

Q: My test shows a mismatch in 1 location between the possible father and the kid, yet the probability of paternity is over 99%. How can this happen?
A: Chances are practiced that in that location was a mutation in either the kid'south or the possible begetter's genetic code at that location. Analysts have mutations into account when doing their calculations and reaching conclusions. So even if there is a mismatch, the man might still be considered the biological begetter of the child tested.
Q: Can your paternity test results be wrong?
A: DDC processes every sample twice, past a separate team of technicians, to eliminate the possibility of human being mistake for extremely authentic results. If your results say that the alleged father is "excluded", this means in that location is zero probability that the person is the biological father, based on the Dna analysis. If your results say that the father is "not excluded", this means that there is nigh 100% probability that the person is the biological male parent – in the instance higher up, a 99.9998% probability. Still, if two possible fathers are close relatives, such as brothers, they share much of the same Dna. It is important to let usa know if two possible fathers are relatives. We tin practise additional testing to increase accuracy in this situation.
Q: Why aren't there names on my paternity test report?
A: When doing an calm test, there are no names on the report, only an identifying number for each set of samples and their function in the test (declared male parent, child, or female parent). We practice this considering we cannot verify whether a sample submitted to us belongs to the person indicated by the customer. Withal, if you cull to do a legal, witnessed, chain-of-custody paternity exam with court-admissible results, then the study includes both names and our visitor branding. For both at-dwelling and legal testing, the testing process itself is exactly the aforementioned, and yous can be sure results are guaranteed accurate for the samples provided to us.
Q: Can the Probability of Paternity ever exist 100%?
A: No. Deoxyribonucleic acid test results are calculated based on statistics. Quite simply, in order to get a 100% probability, nosotros'd have to test every human in the world with a similar ethnic background to the alleged father beingness tested. And for obvious reasons, that's non possible!
