Paternity DNA testing in Ashburn, Virginia is the most commonly requested DNA test. It establishes a biological relationship between a father and child using a painless cheek swab. TestMark DNA collection sites in Ashburn support both legal paternity tests (used for birth certificates, child support, custody, and Social Security) and personal paternity tests for private peace of mind. Legal tests require chain-of-custody documentation and government-issued ID at the collection site.
Immigration DNA testing in Ashburn, Virginia is used by USCIS to verify biological relationships when other documentation is insufficient. TestMark DNA collection sites in Ashburn follow USCIS-accepted chain-of-custody procedures and coordinate sample handling between tested parties, including samples collected at U.S. embassies abroad. Results are delivered directly to the petitioner or the designated USCIS contact. Testing is always initiated at the request of the USCIS officer handling the petition.
Maternity DNA testing in Ashburn, Virginia confirms the biological relationship between a mother and child.

Maternity testing follows the same accurate cheek-swab procedure as paternity testing. Both legal (court-admissible) and personal test options are available at TestMark DNA collection sites in Ashburn.
