DNA paternity tests are used to determine paternity when it’s not clear who the father of a child is. These tests are highly accurate, boasting around a 99.9% accuracy rate. That accuracy rate doesn’t necessarily consider situations where tests have been tampered with or where samples were taken from the wrong people.
For the most part, paternity testing is a simple, definite way of proving parentage. These tests may be performed as cheek swabs or blood tests and should be done in a medical setting. If they aren’t done in a lab directly, there is a greater risk that tampering or sample fraud could occur.
What can you do if you think the paternity test is inaccurate?
If you think the paternity test is inaccurate, you will need to provide evidence for why you believe so. For example, if you think that the wrong child’s cheek was swabbed or that the results were mixed up with another person’s, then it may be reasonable to have the test performed again.
To prevent issues with the samples a second time, it’s worth going to the lab with your child and the other parent. A technician can take the swabs or blood in front of you, so that everyone can see the samples being taken and filed correctly. This should help prevent fraud or any question about the legitimacy of the results.
There are rare cases when the results will come back inaccurate, such as if the father is a twin or a triplet, but, in the majority of situations, the results will be accurate and give you the evidence needed for your custody case.
