For 3 years I was looking for my son's father and going thru buying expensive DNA test until we came across GTL. We ordered the 79$ kit and we did the simple swab. 4 days later we got the results and my son now has his dad in his life. Thank u so much GTL. 5 Stars!!!

Thank you for providing affordable testing for the public. From birth, my sister and I were told we were fraternal - now after 61 years - we have the answer our mother always thought was true. We are identical!

Immigration DNA Testing

immigration.jpgGTL is an approved Immigration and Naturalization Service/Department of Human Services supplier for immigration DNA testing, and provides government agencies, local embassies and immigration clients with result interpretation as requested.

We have competitive DNA testing pricing starting at only $550 for most embassy locations!

In immigration DNA cases either paternity or maternity tests may be performed, or a DNA Relationship Test can be used to identify a biological relationship with a family member other than a mother or father. We may for example be able to test one's aunt or uncle to determine that he or she is related to a niece or nephew.

We provide DNA testing consultation for each immigration test to guide you through the test process, ensuring that the most appropriate family members are selected for verification and accuracy.
