Yes, the test can give the wrong result. DNA Paternity Testing, LLC™ takes many extra precautions during the collection process to insure the integrity of the test is not compromised by careless handling of the specimens. The sample is then placed in a tamper proof package and sent via overnight carrier directly to a lab that is certified and accredited by the American Association of Blood Banks, AABB.
If the child and the tested man do not match at three or more tested DNA locations, then the tested man can not be the biological father of the child.
DNA Paternity Testing, LLC™ guaranties a minimum probability of paternity of 99.99%. At a 99.99% probability of paternity, on average the identified genetic pattern will fit no more than 1 in every 10,000 men. Most of our tests are even more discriminating than that.
