Paternity DNA Testing
Paternity DNA testing in Laurel, Maryland 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 Laurel 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 Laurel, Maryland is used by USCIS to verify biological relationships when other documentation is insufficient. TestMark DNA collection sites in Laurel 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 Laurel, Maryland confirms the biological relationship between a mother and child. It is used in cases of assisted reproduction, adoption reunification, or to confirm a mother's identity when her relationship to a child is uncertain. 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 Laurel.
Sibling DNA testing in Laurel, Maryland determines whether two people share one or both biological parents. It is typically used when the alleged father is unavailable and is especially useful for inheritance claims, Social Security benefits, or establishing family lineage. TestMark DNA collection sites in Laurel support full sibling tests (same mother and father) and half sibling tests (same mother or father only). Including a known parent's sample significantly improves accuracy.
Grandparent DNA testing in Laurel, Maryland establishes a biological relationship between a child and one or both paternal grandparents when the alleged father is unavailable.

Testing both grandparents, where possible, yields the most conclusive results. Both legal and personal grandparent tests are available at TestMark DNA collection sites in Laurel.
