A Paternity Test is a medical test which can be either a blood test or a DNA test to determine the biological father of a child. We are often asked by our clients what exactly the DNA test results of our Paternity Test show, or will look like. This is not performed anywhere in the world. Our paternity test results are extremely accurate even without testing the mother’s sample. There The Combined Paternity Index is a ratio indicating how many times more likely it is that the tested male is the biological father than a randomly-selected unrelated man with a similar ethnic background. These alleles at each STR marker are compared between the donors. Probability of Paternity. Genetic System Table (Locus/Allele chart). Understanding DNA Paternity Test Results Understanding your DNA test results depends on whether they indicate paternity inclusion or exclude paternity. More information on paternity test results can be found in our Learning Center articles Paternity Testing FAQs and DNA Testing FAQs. Example Paternity DNA Test – Inclusion Excluded, indicates that the father is not the biological father, while Non-excluded will indicate the possibility of the father being the biological father is very high.
Is it safe to do a paternity test while pregnant? With current technology, DNA paternity tests results have an accuracy of over 99.99%. The purpose of a paternity test is to determine whether the individuals undergoing this test are the biological parents of a child or not. This is arguably the most important section of a Paternity DNA Test Result. The basic steps of paternity testing involves the extraction, replication and analysis of DNA. On the other hand, if very few people have an allele at this location it’s rarer and the PI value would thus increase. Statement of Results.

known as alleles: one is inherited from the father and the other from the For this, it would be necessary to test the entire DNA profile of the individual. If the tested male is considered the biological father, there is a number listed for the Combined Paternity Index. Genetic System Table (Locus/Allele chart) Combined Direct (Paternity) Index. Our advanced DNA testing technology determines the length of each participants alleles and compares them with the lengths of the alleged father’s alleles to determine the number of matches. Our procedures test for 22 genetic markers and the gender identification marker amelogenin.
This number varies on a case by case basis. The report will show one of two conclusions, an Inclusion and an Exclusion. Detailed Paternity Test Results Report Overview. The paternity test result is provided on a single page.
and sometimes the mother). Privacy Policy | Refund Policy | Terms of Service © 2019 Validity Genetics DNA Services, 201 E Las Cruces Ave #2232, Las Cruces, NM 88001, USA.
The allele of the father and child are compared and determined if they correspond. Below you can find sample reports to see what your result will look like. The paternity index (PI) is a statistical calculation that compares the DNA profiles obtained to an untested random individual within the general population.
For help understanding a Non-Invasive Prenatal Paternity Test report, please contact our prenatal testing specialists at 800-303-9085 (M-F, 8 am to 5 pm Eastern). If two tested individuals match at an allele, it could indeed be because of a parent–child relationship, but it could also be because most people match with this allele at this location. We have therefore included a sample paternity test report to demonstrate what information will be provided in the report. Likewise, when the individual is related to the child the probability of parentage will be 99.99%. We always advise sending in her sample if she is available for the test.
