There are additional testing procedures that must be performed after DNA samples have been properly collected and submitted to a certified lab for paternity testing.

Whether for confirmation of paternity, maternity, genetic relationships, legal requirements or simply peace of mind, once the samples have been delivered to the testing facility, the actions performed and the results provided are beyond the control of the potential biological parents, relatives, lawyers and all government agencies.

This is EXACTLY how it should be so as to ensure that the samples have not been tampered with, the identities of those submitting the samples are confirmed and that there is no abuse or interference with how the DNA testing lab conducts the tests and the lab analysis provided.

Confirming DNA Samples and Preparation for Testing

It is not necessary for any one submitting to a DNA test to fully understand the procedures involved in preparation of the samples for testing. The information provided is provided for those wishing to comprehend how such lab testing is performed.

What is likely far more important is to establish a communication interface between the testing laboratory, legal representatives and the individuals requesting the DNA analysis. This is highly warranted in legal cases involving paternity identification, child custody issues and financial support concerns.

Laboratory Analysis Methods

I asked this question in the pregnancy section and got little joy. What I want to know is could a DNA paternity test result by buccal swab be wrong if done in a reputable lab?

I have heard of things such as contamination and DNA mutation of the father between conception and test date (18 months on).

The sample has been in the lab over a month now awaiting the other sample to be tested. It says not to eat or smoke before, what impact could this have and is human error more common than they lead us to believe or do they even know 99.99% if they are correct?

Interested to know anybodys opinions please who is in the know.

The father of my daughter took a DNA paternity test without me and the results were inconclusive.

Now the lab has requested my boyfriend’s father to come in and give a DNA sample to clear this up.

The lab said that there was no problems with the sample. They said that the results were less than 85% and therefore need the paternal grandfather to come in for further testing.

They also said that they looked at 15 different areas and tested the 15 areas 3 times and yielded the same response.

Thank you in advance for helpful advice.
