TestMark DNA schedules chain-of-custody DNA collections in Dover, Delaware at 850 S. State St., Dover, DE 19901, an office building in the Morris Estates neighborhood a few blocks down South State Street from Bayhealth Hospital, Kent Campus. Each collection is ordered and booked through TestMark DNA, and the city has a second site at 200 Banning Street.
Number 850 South State Street is an office building in the Morris Estates neighborhood of south Dover, and the collection site shares the address with Aloe & Carr, an endodontic practice whose Dover office is in the same building. Bayhealth Hospital, Kent Campus, the former Kent General Hospital, stands a few blocks back up South State Street at number 640, so anyone who already knows the way to the hospital is nearly there. Morris Estates itself is a quiet residential area made up mostly of single-family homes, so expect an office setting on a neighborhood stretch of State Street rather than a hospital lobby. TestMark DNA books each chain-of-custody collection at this address, prepares the paperwork that travels with the samples, and ships them to the laboratory.
Dover has a second TestMark DNA collection site at 200 Banning Street, and the network continues north to Smyrna and south to Milford, so Kent County families can be booked at whichever address suits their day. When a test is tied to a Kent County case, the two offices people deal with are both on South Governors Avenue: Family Court, Kent County, at 445 S. Governors Ave., which has a free parking garage beside the courthouse, and the Division of Child Support Services Dover Office at 905 S. Governors Ave.
TestMark DNA's South State Street site in Dover is at 850 South State Street, a few blocks down the road from Bayhealth Hospital's Kent Campus.

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.
