Common DNA Tests Used in Immigration Cases
Many of the DNA tests available on the market today are useful for providing biological evidence for
immigration cases. If an immigration office or embassy feels that more evidence is necessary, they may
request that you participate in a DNA test that best fits their needs and the type of relationship(s) —
parent, sibling, grandparent — they need to prove.
Specifically, tests that immigrants and refugees may be asked to take include:
- Paternity Test - To verify the biological relationship between an alleged father and a child using DNA samples.
- Maternity Test - To verify the biological relationship between an alleged mother and a child using DNA samples.
- Grandparentage Test - To verify the biological relationship between grandparents and their grandchild using DNA samples.
This test is often used to indirectly determine the paternity of a child when the alleged father is missing.
- Siblingship Test - To determine if two individuals are biological siblings using DNA samples.
- Twin Zygosity Test - To determine if twins are identical or fraternal.
- Y-STR Test - To verify biological relationships between males, based on the Y chromosome.
- mtDNA Test - To determine if people are biologically related through the maternal genetic line.
