Understanding your Paternity Test Results
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 has a 0% of probability,” this means that he cannot be the father because the analysis shows that they do not share a paternity relationship.
Or, if it reads “IS NOT EXCLUDED as the biological father, the Combined Parentage Index (CPI) is 100 (or higher) and has a 99% (or greater) probability,” this means that he is considered to be the father because the analysis shows that they share a paternity relationship.
