Just How Accurate Are DNA Paternity Tests?

One of the first questions that people ask with regard to DNA testing is how accurate are the results? While it’s true that no single positive test can ever be 100% accurate, a DNA paternity test is about as close as it gets. The criteria behind the accuracy of the test lies with the number of loci that are being analyzed. These are the number of points found on each DNA segment. Therefore the higher the number of loci (points), the more accurate the data will be. With this in mind, anyone seeking a DNA test should make sure that they choose a laboratory or company that tests a minimum of 13 loci. Many labs or companies will look to test at least 16 loci for greater accuracy.

In essence there are two different types of paternity test results, with one being known as exclusive and the other being known as inclusive.

Exclusive Paternity Results

If a test shows that a person is not the biological father of a child, this is known as an exclusive paternity result. This means that the DNA samples taken from the father did not in any way correspond with those of the child. Is this is the case, these results should always be 100% correct. If a man has been excluded from being the father of the child, then the tests has to show with 100% accuracy that there is no way that he physically can be.

Inclusive Paternity Results

The other type of test result is an inclusive test. This differs in the way that the testing refers directly to the likelihood that the man is the father of the child. No test of this nature can ever be 100% accurate, and inclusive results should be shown to be at least 99% accurate. In many cases they are nearer 99.99%.

Strengthening Bonds

Contrary to popular belief a paternity test can actually bring those people in question closer together. It can put an end to accusations and bitterness as well as igniting a strong bond between the father and child. In many cases a positive test can also help to strengthen the bond between the child’s biological mother and father as they have a common goal in working together to do what’s best for the child.

Nowadays, you don’t have to go to a laboratory to undergo DNA paternity testing. Instead there are many companies like Easy DNA who will send you the tools necessary to carry out the tests in the comfort of your own environment. These tests are often carried out using a simple oral swab technique. Results are then sent back and examined under laboratory conditions making the whole process easy, discreet and pain free.
