• $79 DNA Paternity Test

Our paternity DNA testing services are designed to make determining paternity as quick and simple as possible. Our DNA paternity test options include either our $79 informational paternity test kit or our $230 court-admissable legal test. Legal paternity testing is important if you intend to present your paternity test results in court. Learn more about our DNA paternity testing.

• DNA Predisposition Test

  • The kit includes a DNA testing service that reveals your genetic predisposition for 25 diseases and conditions. The most common and significant conditions are always the ones first studied by scientists, and consequently their genetic causes were discovered first. In fact, the conditions covered by this service account for 75% of all causes of natural deaths in the English-speaking world, implying a strong and meaningful coverage. Learn more about the DNA Predisposition testing.

    See the DNA Predisposition Test page for more information.

• Collect and Send DNA Test

  • If time is a factor, our Collect and Send DNA Test enables you to simply collect a DNA sample and send it to our Genetic Testing Laboratories. With this DNA paternity testing option, you will not have to wait for your DNA paternity testing kit to be delivered or be concerned about the discretion of the testing kit arriving at your home or office. By collecting a sample from each participant and mailing them into our testing laboratory, you can discover the truth quickly and simply. Learn more about the GTL Collect and Sent DNA Test.

• Siblingship DNA Test

  • Our DNA siblingship tests can help you determine the statistical probability that siblings share the same parents or if two individuals are in fact, related siblings. Unlike our paternity tests, siblingship DNA tests are unable to provide a conclusive result. The test is able to determine the probability of relatedness, however by testing one common parent, the test is much more determinant. Read more about our siblingship DNA tests.

• Grandparentage DNA Test

  • The GTL grandparentage DNA test will determine the statistical probability that an adult is the grandparent of a child. This type of avuncular DNA test can determine the probability that an adult in that grandparent of a child. Unfortunately, because of the relationship, conclusive results cannot be derived. The accuracy of the test is increased if one of the child's parents is also tested. Read more information about our grandparentage DNA test.

• Aunt & Uncle DNA Testing

  • Similar to our grandparentage DNA tests, our Aunt and Uncle DNA testing identifies the avuncular relationship between a child and possible aunts and uncles. To increase the accuracy of this DNA test, it is advised that one of the child's biological parents also participate in the test. Find out more information about our Aunt & Uncle DNA testing.

    Includes: Parent, child, and one aunt or uncle (Parent optional)	$150: Informational

Determining paternity or maternity is done by examining the DNA provided by the paternal or maternal grandparents. There are other options if these individuals are not available for testing. Learn more about our missing parent DNA test and the other options available to those in this situation.
