How do you find out the results of a DNA paternity test are false?

DNA paternity tests are highly accurate and reliable, with a false positive rate of less than 1%. However, there are a few factors that could lead to a false negative result, such as:

* Sample contamination: If the DNA samples from the mother, alleged father, and child are not properly collected and stored, they can become contaminated with DNA from another person, leading to an inaccurate result.

* A mutation in the DNA of the child: In rare cases, a child may have a mutation in their DNA that prevents their DNA from matching that of their biological parents.

* A chromosomal abnormality: A chromosomal abnormality, such as a translocation or deletion, can also lead to an inaccurate DNA paternity test result.

* Consanguinity between parents: If the biological parents are closely related (e.g., siblings or half-siblings), they may share more DNA in common than expected, leading to an incorrect conclusion.

If you have any concerns about the results of a DNA paternity test, it is important to speak to a qualified genetic counsellor or medical professional. They can help you understand the results and determine if further testing is necessary.
