We follow all paternity-test guidelines for the language used in the report. For this reason, your paternity test results will say whether the possible father IS EXCLUDED or IS NOT EXCLUDED as the biological father of the child tested.
- IS EXCLUDED: Means that he cannot be the father because testing determined that he and the child do not share a biological parent/child relationship.
- IS NOT EXCLUDED: Means that he is likely to be the biological father because testing determined that he and the child do share a biological parent/child relationship with a high degree of probability.
A paternity test result includes a table that lists:
- The allele sizes of the different DNA markers examined and used in the statistical analysis portion of the test (i.e., the DNA profile)
- A Probability of Paternity value
- A Combined Paternity Index (CPI) value
You will want to focus on the probability of paternity percentage. A result of 0% means the alleged father is not the biological father; a result of 99.99% or higher means the alleged father is most likely the biological father. The CPI value represents the odds against another random, unrelated, untested male in the population having the same results as the tested man. IMPORTANT: Paternity testing is calculated using statistics. Therefore, a probability of paternity can never be 100%, because that perfect score would require testing every man on earth with the same racial background of the man tested—which isn’t possible. A probability of 99%+ is considered conclusive for paternity.
