Maternity DNA Test
Designed to determine if a woman is the biological mother of a child. DNA samples can be taken from just the alleged mother and child, or may also include the father.

Avuncular DNA Test
An avuncular test involves testing the child’s paternal aunt or uncle (the alleged father’s sister or brother). Including the mother in this test is strongly recommended as it strengthens the genetic evidence. Generally, this test will not give results as strong as a grandparentage test, but it is still a good option if the only people available for testing are the alleged father's siblings.

 Grandparentage DNA Test
A grandparentage test is often one of the better relationship tests to perform to determine paternity of a child. The best testing scenario is a test which includes the mother, child and both of the alleged father’s parents (the child’s paternal grandmother and grandfather). By including both of the alleged father’s parents, the alleged father’s DNA profile can be reconstructed. Comparing the alleged father’s reconstructed profile against the child’s DNA, can allow this testing scenario to give results as accurate as a paternity test. Each time a person is removed from the test, such as a grandparent or mother, the strength of the genetic evidence decreases, therefore testing all 4 individuals is the best testing option
