How to Read Paternity Test Codes
How do I read and understand my paternity test results? Following paternity testing guidelines, paternity results show whether the possible father IS EXCLUDED or IS NOT EXCLUDED as the biological father. For example: If the paternity test result reads IS EXCLUDED as the biological father, the Combined Parentage Index (CPI) is 0 and means that he cannot be the father because the analysis shows that . Mar 04, · How do I read a paternity test? When the results letter is presented after the paternity test is complete there will be several portions of the letter that may appear written in Latin. With words like loci, inclusion, exclusion, and trio - it takes a bit .
In most cases a DNA paternity test will provide a conclusive result. The tests are based on the analysis of 20 genetic loci, each compared separately to obtain a paternity index the 21st loci is the Amelogenin sex loci to confirm how to read paternity results sex of the donor. The CPI represents the Probability of Paternity POP and is calculated on the basis of how common the genetic information found in your analysis is compared with the general population. The CPI can result in a One must always look at the combined paternity index CPI to help make results more understandable.
An exclusion is reported with a POP of 0. In an exclusion result, it will be seen that with at least two genetic markers, there is a non-match. When an exclusion is reported, a second, independent test is normally performed to confirm the initial result.
Another possibility is that it could be an inclusion with a mutation. Known mutations have a specific frequency in various racial populations and, often, that frequency is low. To confirm mutations, it is always recommended that the mother is tested, if she has not already been included, or to what colour robes do buddhist monks wear extended testing of additional markers to help improve the statistical value of the result.

DNA Paternity Testing
Reading a paternity test results can be a very very hard thing to do especially if you don’t understand what the numbers on the result actually means. Today, we’re going to delve in a little bit on what exactly a paternity test is in a bit more detail. In the video below, Dr. Courtney Harrington breakdown The specifics of the numbers on the paternity test result. The probability of paternity in this case would be 0% and the Statement of Results on the report will read “The alleged father is excluded as the biological father of the tested child. This conclusion is based on the non-matching alleles observed at the STR loci listed above . Jan 16, · The CPI represents the Probability of Paternity (POP) and is calculated on the basis of how common the genetic information found in your analysis is compared with the general population. The CPI can result in a %+ Probability of Paternity. Both the CPI and the Probability of Paternity should be quoted in a paternity test result.
Understanding your DNA test results is fairly straightforward once you know what data the results actually give you. For many people, this will be the first time they have undergone any form of DNA test, so the following information will help you to understand the test results. So that paternity can be determined, samples of DNA from both the child and the alleged father are needed.
When the DNA samples have been obtained, the genetic blueprints are extracted using a form of biochemical technology known as PCR polymerase chain reaction , and then compared with each other.
Babies inherit 23 chromosomes from their mother and 23 from their father, making 46 in total. Depending on your individual needs, there are different Paternity Tests from which to choose. Sometimes, an individual simply wants a paternity test for their own peace of mind, and for this purpose, a Home Paternity Test Kit can be used. If a DNA test is required for legal purposes or is needed in an immigration case , then more stringent collection methods need to be used so that the results will stand up as evidence in a court of law.
In the test, 21 genetic markers are compared between the alleged father and the child to determine whether or not they match. Only 20 of these genetic markers are actually compared, because the twenty first is only included to ensure that there has been no mistake in the labeling of the sample in a home DNA test.
This last genetic marker is called the amelogenin sex gene and determines gender. Understanding your DNA test results depends on whether they indicate paternity inclusion or exclude paternity. The extracted genetic markers from the DNA samples are represented in a table, listing each marker. The report you receive includes this table, and the results for the child, the alleged father and the mother if she is tested, are displayed in separate columns.
In this case, the probability will be in excess of Based on the analysis of STR loci listed above, the probability of paternity is This conclusion is based on the non-matching alleles observed at the STR loci listed above with a DI equal to 0. The results are calculated using a complex statistical analysis, known as the Combined Paternity Index or Combined Direct Index. This indicates the probability of paternity from the tested sample, compared with the probability that a random man from the same ethnic group is the father.
