What Is a Legal DNA Paternity Test?
A DNA paternity test compares a child's DNA profile with that of the possible father to determine if there is a match. A legal paternity test is valuable because you can use the test results in court. Unlike the tests you can take at home, where the people tested can't be legally identified. This test will give you THE answer in a legal document. Legal DNA paternity tests include verifying participant IDs, witnessed DNA collection by an approved and impartial party, and a strict chain of custody.

What Is a Standard Non-Legal DNA Paternity Test?
If you want accurate paternity answers fast but don't need results for legal reasons like child support or custody, a standard DNA paternity test kit is the solution. A standard DNA paternity test is only for personal knowledge and peace of mind.

Siblingship Testing Services
A DNA siblingship analysis compares the DNA of one person to that of another to determine the likelihood that they are related biologically as siblings by calculating the statistical probability that the parties share the same two parents, one parent, or no parent at all.
Testing one or both of the known parents is always recommended to receive the most accurate results possible. However, it can still be completed when the alleged parents are unavailable for testing. Siblingship test results are best related in probability and can fall between 0% and 99.99%. The higher the percentage, the more likely the tested individuals are related; however, some results may be inconclusive. In a sibling DNA test, the degree of certainty that can be achieved depends upon who is available for testing and the specific type of sibling relationship being tested. Generally, the more genetic information available, the greater the chance the test will be conclusive.
Individuals who share both biological parents are called full siblings and share around 50% of their genes. Individuals who share only one biological parent are called half-siblings and share around 25% of their genes.
Three different types of statistical analyses can be performed for DNA sibling tests, which are based on the particular parental relationship(s) in question:
Full Siblings vs. Unrelated- In these sibling tests, the DNA of two individuals is compared to determine the likelihood that they have the same biological mother and father versus being completely unrelated.
Full Siblings vs. Half Siblings- In these sibling tests, the DNA of two individuals with the same biological mother is compared to determine the likelihood of having the same biological father. We recommend testing samples from the biological mother to increase accuracy.
Half Siblings vs. Unrelated- In these sibling tests, the DNA of two individuals with different biological mothers is compared to determine the likelihood of having the same biological father. We recommend testing samples from at least one—preferably both—biological mothers to increase accuracy.
Grandparent DNA Test
A grandparent DNA test calculates the likelihood of relatedness between a child and one or both grandparents. A child inherits 50% of its genes from its biological mother and 50% from its biological father; that child shares precisely 25% of its genes with each biological grandparent. Suppose both biological parents of the alleged parent are tested and do not possess the paternal or maternal genes between them. In that case, they are excluded and ruled out as the biological grandparents. When both biological parents of the alleged parent possess the paternal or maternal genes between them, they are not excluded as the biological grandparents.
It may not be possible to obtain conclusive results in a grandparent DNA test if both alleged grandparents are not tested. We recommend testing both alleged grandparents and one parent if possible to achieve the most accurate results, similar to the Missing Parent DNA test.
It is also essential to understand that, in reporting the results of a DNA grandparent test, the laboratory assumes that the tested alleged grandparents are, in fact, the biological parents of the unavailable alleged parent. If there is any question regarding the paternity of the unavailable alleged parent, then the suspected biological grandparent should not be tested.
Avuncular Testing Services
Avuncular tests calculate the likelihood of relatedness between a child and an aunt or uncle. A child inherits precisely half of their genes from their biological father, and the biological father shares around half of his genes in common with his full sibling. Therefore, the child will share around half of its paternal genes in common with the full sibling of the biological father. Based on the number of genetic matches, the laboratory calculates the statistical likelihood that the alleged aunt/uncle is biologically related to the child versus unrelated.
It may not be possible to achieve a conclusive result. Even though the siblings may have the same biological parents, the alleged father is not genetically identical to the alleged sibling and has different genetic markers. On average, testing a suspected father's full sibling allows us to determine only half of his genes. Testing the child's mother is strongly recommended to increase the certainty of the results, as this allows for identifying genetic markers of the child that were inherited maternally.
Missing Parent Testing Services
When the alleged parent is either missing or deceased, and both suspected grandparents are available for testing, a missing parent analysis can be performed. Including the child's mother is not required but is highly recommended to achieve the most accurate results.
Because a child inherits precisely 50% of its genes from its biological mother and 50% from its biological father, it shares precisely 25% of its genes with each biological grandparent. If both biological parents of the alleged father are tested and do not possess the paternal genes between them, they are excluded (ruled out) as the biological grandparents. When both biological parents of the alleged father possess the paternal genes between them, they are not excluded as the biological grandparents.
