Paternity (DNA) Testing, and other kin

Paternity (DNA) Testing, and other kin

Paternity and other family tests are available

There are various DNA tests you can have done. Grandpaternity, Infidelity, maternity, paternity, prenatal paternity, and siblingship. This is the breakdown of the different tests that can be administered.


Grandpaternity: This test compares the DNA from a child to his/her biological mother, as well as at least one of the biological paternal grandparents. Since the father would have inherited 1/2 of his DNA from his mother, and 1/2 from his father, it is preferable to include both biological grandparents in this test. 


Infidelity: This test compares DNA that is extracted from an item that has been submitted to a known sample. The two are then compared to see if there is a match. This is usually used if you suspect a spouse of infidelity. Although the results are not admissible in a court trial, it will give you peace of mind.


Maternity: This test is used to determine the probability of maternity by comparing the DNA from the child to that of the alleged mother.


Paternity: This test is used to determine the probability of paternity by comparison of the DNA of the child to that of the alleged father.


Prenatal Paternity: This test is administered when waiting for determination of the biological father of the child is not an option. It is a non-invasive test that poses no risk to the unborn child and can be determined as early as 9 weeks of pregnancy.


Siblingship: This test compares the DNA from a shared biological mother to that of the sibling in question, and one or more known full or half-siblings to determine the likelihood that the unknown sibling is a full, or half-sibling, or unrelated.
