Paternity Test (father and child):

Paternity testing establishes whether a man is the biological father of one or more children. A paternity test includes a Wfg Consumer Test Kit for the putative father and each of the children to be tested. An additional kit can be ordered to include the mother in the test.

Maternity Test (mother and child):

Maternity testing establishes whether a woman is the biological mother of one or more children. A maternity test includes a Wfg Consumer Test Kit for the putative mother and each of the children to be tested. An additional kit can be ordered to include the father in the test.

Sibling Test:

Full siblings (brother/sister) share two biological parents. Based on the amount of shared DNA between individuals, the probability of a sibling relationship is calculated. A sibling test includes a Wfg Consumer Test Kit for each putative sibling.

Half-Sibling Test:

Half-siblings (half-bother/half-sister) share one biological parent. Based on the amount of shared DNA between individuals, the probability of a half-sibling relationship is calculated. A half-sibling test includes a Wfg Consumer Test Kit for each putative half-sibling.

Twin Test:

Twin DNA testing will determine the likelihood that two individuals are identical twins relative to the likelihood that they are fraternal (non-identical) twins. Identical twins have the exact same DNA profile, while fraternal twins share DNA, but do not have the same DNA profile. A twin test includes a Wfg Consumer Test Kit for each twin.

Aunt or Uncle Test (aunt or uncle and niece or nephew):

Full-aunt / full-uncle means that the putative aunt/uncle shares both parents with the biological parents of the niece/nephew. Half-aunt/uncle means that the putative aunt/uncle shares one biological parent with the biological parents of the niece/nephew. Based on the amount of shared DNA between the putative aunt/uncle and the niece/nephew, the probability of a full aunt/uncle or half aunt/uncle relationship is calculated. The test includes a Wfg Consumer Test Kit for one aunt/uncle (full or half) and one niece/nephew (full or half).

Grandparent Test (grandparent and grandchild):

Grandparentage testing is useful when the biological parents are not available for testing. Based on the amount of shared DNA between the putative grandparent and a child, the probability of a grandparent relationship is calculated. A standard grandparent test includes a Wfg Consumer Test Kit for the putative grandparent and the child. Additional kits can be ordered for the other putative grandparent or additional children.

Y-STR Haplotype Test:

Y-STR haplotype testing is for males only and is used to establish paternal lineages. This testing does not determine the specific relationship between males but maybe useful for genealogical purposes.

Human Cell Line Authentication (CLA) Test:

STR (short tandem repeat) testing is the gold-standard in authenticating and validating human cell lines. One CLA Kit is required for each human cell line to be tested. Easy to follow instructions are included. Results are emailed approximately 10 days after the CLA Kit is returned to the Wfg laboratory.
