Accuracy and Reliability of Paternity Test Results

A Paternity test result is extremely accurate and reliable. Be sure to choose a leading company for paternity testing in Canada so as to ensure accuracy and reliability.

Today’s DNA testing technique, using what is known as PCR or polymerase chain reaction, means geneticists can work with tiny quantities and sometimes even degraded DNA samples to provide results that are precise and scientifically sound.

Who needs to be tested?

With the inclusion of samples from the alleged father, the biological mother of the child, and

the child you can definitely expect a probability of paternity in excess of 99.99%. This percentage expressed of 99.99% is referred to as an “inclusion of paternity”; in such cases, the alleged father and child will have a matching DNA profile which clearly means that the tested father is, in fact, the biological father. Typically, DNA testing kits are packed with swabs to for the mother’s sample in case she is available to participate in the test.

Motherless DNA paternity tests

You do not necessarily need to include the mother’s sample for a conclusive paternity test; in fact, the majority of paternity tests are “motherless”, that is, they are done without the inclusion of the mother’s sample. Having the mother’s sample will however, provide a more accurate result. There are many cases in which it may not be possible to include her samples. Even a duo paternity test (a paternity test with only alleged father and child’s DNA samples)will provide an inclusion of paternity in excess of 99.9% – still a very conclusive result that is undisputable even to a court of law.

When the alleged father is not the biological father: he will be excluded with a 100% probability. Your paternity test result will show the probability of paternity to be 0%. This incontrovertible result shows that the man tested CANNOT be the biological father. Browse our frequent paternity testing questions for more information.

Can I do a prenatal paternity test?

Yes, you can carry out a prenatal paternity test if you do not wish to wait till the birth of the baby. Procedures required to procure samples of fetal DNA are however, considered risky and can have unpleasant side effects. Such procedures include amniocentesis and chorionic villus sampling. Besides having certain risks, they can be rather costly and require the laboratory to analyse the samples quickly. There are also non invasive prenatal paternity tests which are highly accurate and just as importantly, 100% safe for the mother and the baby. The test requires blood draws from the mother and alleged father/s. This paternity test in pregnancy can moreover be done at just 10 weeks of pregnancy.

How can I be sure that results will be accurate?

In order to ensure that your paternity test has the standards of reliability and accuracy reported above you need to make sure that the laboratory carrying out your test is accredited. One of the most important international laboratory accreditations is the ISO 17025 accreditation. This is one of the most internationally recognized accreditations awarded to those laboratories that show consistently high standards in DNA testing and outstanding technical competence.

All laboratories used by easyDNA, our partner company, make use exclusively of laboratories that are accredited, in order to provide their customers with a guarantee of accuracy and reliability of results. Feel free to Contact us for more information.>
