Relationship DNA Testing
DNA testing can answer more than paternity questions. Explore sibling, grandparent and other biological relationship testing when the parent needed for a standard paternity case is unavailable or another family relationship is being evaluated.
Good fit for
Sibling, grandparent and other relationship DNA testing through approved laboratory partners, with mobile collection options where available.
Relationship DNA testing evaluates biological relationships beyond a standard paternity case. The right test depends on which relatives are available and whether the result is for personal knowledge or official use.
Sometimes the question is not “is this the father?”
Relationship DNA testing can evaluate other biological relationships when the people available for testing differ from a standard parent-child case. The correct test depends on who is available, the relationship being evaluated and the purpose of the result.
Choose the case before choosing the kit.
Sibling, grandparent and extended-family testing use different statistical models and may require different combinations of participants. Caliber Ready routes the request to the appropriate partner-lab workflow rather than forcing every family situation into a paternity product.
Personal and legal use still matter.
If the result will be submitted to a court, agency or other official process, tell us before collection so the required identity and chain-of-custody workflow can be confirmed.
