Maternity

Maternity DNA testing can confirm a maternal relationship for immigration, prove an adoptee’s relationship with their biological birth mother, and more.

$

Grandparent

If a possible father is not available for paternity testing, a grandparent test can confirm a family relationship instead. One or both paternal grandparents can participate.

$

Siblings

When two people are trying to determine if they share the same father and the father isn’t available for testing, a sibling DNA test is an effective alternative.

$

Twins

A twins test (also called twin zygosity) is a DNA analysis that definitively shows whether twins are identical or fraternal. Only DNA can tell for sure.

$

DNA Reconstruction

This series of DNA tests confirms biological family relationships and is most often used to determine if a child is related to a possible father’s close relatives.

$

Avuncular

This test is a good option when the father is not available for testing, and the only relative available is a single sibling (brother or sister) of the father.

$

Male Lineage

A Y-STR comparison test can tell you whether or not a child is related to the alleged father’s brother(s) and other male relatives who share a common paternal line.

$

Female Lineage

The mtDNA comparison DNA test can confirm your relationship to long-lost relatives and possible ancestors through the maternal/female line.
