Paternity Test

LEGAL $340.00 | HOME $250.00

DNA paternity testing determines whether a man could be the biological father of a child. We all inherit our DNA (the genetic material) from our biological parents. A DNA paternity test compares a child’s DNA pattern with that of the alleged father to check for evidence of this inheritance—the most definitive proof of a biological relationship. We have collection sites available nationwide.

The result of a DNA paternity test is either an exclusion (the alleged father is not the biological father), or an inclusion (the alleged father is considered the biological father). For a standard paternity test, DDC guarantees at least 99.99% probability of paternity for inclusions or 100% certainty of exclusion.

Test Types: Legal and Home DNA Test

The type of paternity test you need will depend on what you intend to use the DNA test results for:

Unlike the Home DNA Test, where tested parties collect their own samples at their convenience, the Legal DNA Test follows a Chain of Custody documentation process to ensure that you receive accurate and legally defensible results. When you set up your case with ON DEMAND MEDICAL TESTING we will coordinate a convenient sample collection appointment at one of our nationwide sites, during which a trained sample collector will complete all the necessary documentation to satisfy chain of custody requirements.

If you have determined that you do not need a DNA test for a legal matter — and only want to take a paternity test strictly for your own knowledge — a home DNA test might be an appropriate option for you. In a home DNA test, the tested parties collect the DNA samples themselves, at a time and place of their choosing. You can simply call or come by our office or place an online paternity test order, and we will send you the kit in discreet packaging.

Please note that the results of a home DNA test cannot be used as legal proof of paternity, because the identity of the persons tested cannot be verified.


Prenatal Paternity Test                                                 



Maternity Test


Maternity DNA testing determines whether a woman could be the biological mother of a child. Like a DNA paternity test, it compares a child’s DNA pattern with that of the alleged mother to determine how likely it is that the child has inherited the DNA from the alleged mother.

Maternity test results may be used in the following circumstances:

In a maternity test, the child, alleged mother, and biological father are tested. The father’s participation in the maternity test helps to exclude half of the child’s DNA, leaving the rest for comparison with the alleged mother. If the father is not available, we can perform a fatherless test, which involves additional analysis, without additional charge.


Grandparentage Test (Paternal)                                                         

With Mother $650 | Without Mother $775

A grand-parentage DNA test determines whether a couple could be the biological grandparents of a child. It is an indirect way to determine family relationships when an alleged father is not available for a paternity test. Grandparentage test results may be used as proof in Social Security benefit and other inheritance claims as well as in some immigration cases.

In the test, the child’s DNA profile is compared with the DNA profiles of the alleged father’s biological parents. Since a child inherits half of his/her DNA from the mother (maternal side) and half from the father (paternal side), the paternal half should match DNA passed down from the alleged grandparents. The mother’s participation is encouraged to expedite analysis; motherless grand-parentage tests take longer to complete because of the extended analysis required.
