DNA test pricing in Ellicott City, Maryland depends on the specific test you need. Call TestMark DNA for a free consultation. We will confirm the exact price for your situation before you visit the collection site.
Paternity, maternity, sibling, grandparent, immigration, and home kit tests are each priced differently. Legal (court-admissible) tests cost more than personal-knowledge tests because they include chain-of-custody documentation.
DNA paternity and relationship testing is classified as a non-medical test and is not reimbursed by health insurance plans. Payment is collected directly at the time of testing.
We walk you through pricing on the phone before you commit. There is no charge to call, no charge to ask questions, and no obligation to book a test after the consultation.
Tests that involve additional parties (for example, a paternity test that also includes the mother, or sibling tests with multiple siblings) often qualify for a per-person discount. Confirm by phone before your appointment.
