Location Map
In Princeton, West Virginia, TestMark DNA schedules legal (chain-of-custody) DNA collections at 150 Courthouse Road, Suite 102, inside the Courthouse Square medical office building at Morrison Drive. It is the only TestMark DNA collection site in Mercer County, and TestMark DNA orders the test and books your collection time before you visit.
Suite 102 at 150 Courthouse Road is inside Courthouse Square, a three-story brick medical office building on a parcel at Morrison Drive and Courthouse Road in Princeton. Mercer County property records list it at roughly 45,700 square feet, built in 2017 on 1.99 acres with its own paved parking lot. Several health practices share the address, including the Princeton VA Clinic, operated by VA Beckley health care, and CAMC Primary Care - Princeton in Suite 301-B. Despite the street name, this is a medical building, not the county courthouse. TestMark DNA orders each chain-of-custody collection, books the time slot at Suite 102, and has the paperwork prepared before you arrive, so the only thing left to find is the suite door.
This is the only TestMark DNA collection site in Mercer County. The next closest TestMark sites are across the state line in Bluefield, Virginia, and north in Beckley. Mercer and McDowell counties together form West Virginia's Twelfth Family Court Circuit; in Mercer County the family court sits in the Courthouse Annex at 120 Scott Street.

Do I need a doctor's order or court order for DNA testing in West Virginia?
A doctor's order is generally not required. However, if you are a New York State resident, a prescription, court order, or ordering by other authorized persons is required by state law for all DNA identity or relationship tests.
Can DNA testing be done without the mother present?
Yes. A DNA paternity test can be performed without a sample from the child's biological mother. Including the mother's sample is preferred when possible as it improves accuracy.
How long do DNA test results take near Princeton?
Results for a standard DNA paternity test are typically returned within 3 to 5 business days from when all samples are received at the laboratory.
Is DNA testing confidential?
Yes. All samples are packaged in tamper-proof bags and processed at an accredited laboratory with restricted access. Results are shared only with authorized individuals and are never released over the phone.
What type of sample is collected for a DNA test?
The standard sample is a buccal swab - a cotton swab rubbed gently inside the inner cheek. It is painless, non-invasive, and provides the same accuracy as a blood sample.
Will DNA test results be accepted in court?
Results from a legal DNA paternity test performed at an accredited facility may be accepted in court, provided the chain-of-custody form was completed according to laboratory guidelines. Non-legal test results are not intended for court use.
Is DNA paternity testing covered by health insurance?
DNA paternity testing is considered a non-medical test and is not covered by health insurance plans.
