A paternity test is very accurate
As for the accuracy of DNA analysis techniques, it is known that paternity tests are 100% accurate when discarding someone (by saying someone is not the child’s biological father) and between 99.99% and 99.9999% accurate when confirming whether someone is the child’s biological father. There are rare cases where the accuracy of a result may be less than 99.99 percent, for example, if both alleged parents are siblings, then the accuracy of the test may decrease due to the genetic similarity of the siblings. In terms of human error on the part of the testing company involved, the procedures and techniques used by accredited paternity testing companies are strictly regulated, which makes it virtually impossible for “confusion” to occur. We have not found a single occurrence of a paternity testing company that results in an incorrect result due to an error in the end. The most common reason for a questionable result is that the samples have been handled by the participants.
Typical examples of manipulation:
– Alleged parents who provide a sample of their male friend instead of themselves to falsify a false result.
–Mothers who exchange the presumed father’s sample for a sample of one of their male friends to falsify a false result.
– Alleged parents who provide a sample of her friend instead of themselves to falsify a false result.
– Mothers who provide a sample of an alleged father who is actually another sample of themselves to falsify a positive result.
