Order Your Legal Test OnlineWhat Makes a DNA Test Legal?
A legal DNA test uses the same lab science as any other test. What makes it court-admissible is the chain of custody, a documented process that proves exactly who was tested.
1
Verified Identity
A neutral, trained collector checks each participant's government-issued photo ID and photographs them. No one can be tested anonymously.
2
Witnessed Collection
The collector performs the cheek swab in person and documents every step, so there is no question about whose DNA was sampled.
3
Sealed & Tracked
Samples are sealed in tamper-evident packaging and tracked to an AABB-accredited lab, creating an unbroken paper trail courts accept.

Frequently Asked Questions
What makes a DNA test legally admissible in court?
A DNA test is legally admissible when it follows a documented chain of custody. That means a neutral, trained collector verifies each participant's government-issued photo ID, collects the samples, and seals them in tamper-evident packaging that is tracked all the way to an accredited laboratory. A home test you collect yourself cannot be used in court because there is no proof of who was tested.
Is a legal DNA test accepted in all 50 states?
Yes. TestMark DNA uses AABB-accredited laboratories and chain-of-custody collection that courts, agencies, and USCIS accept nationwide. Requirements can vary slightly by state and by the court or agency requesting the test, so call (888) 255-7944 and we will confirm exactly what your situation requires.
How long does a legal DNA test take?
Most legal DNA test results are ready within 3 to 5 business days after all samples reach the laboratory. The collection appointment itself takes about 15 to 20 minutes. Ask about expedited processing if you have a court date approaching.
Do I need an appointment, and what should I bring?
Yes, legal tests are done by appointment at a certified collection site so a trained collector can document the chain of custody. Each adult participant must bring a valid government-issued photo ID. For a minor child, the parent or guardian provides consent and the child's identification or birth certificate.
Does the mother need to be tested for a legal paternity test?
No. A legal paternity test can be completed with just the alleged father and the child and still exceeds 99.99% accuracy. Including the mother's sample can strengthen the statistical result but is not required by the laboratory.
How much does a legal DNA test cost?
Cost depends on the test type and the number of participants. Legal tests include chain-of-custody documentation, so they are priced differently than personal tests. There are no hidden fees. Call (888) 255-7944 for a free consultation and we will give you exact pricing before you book.
Can I use the results for immigration or a passport?
Yes, when the test is ordered correctly for that purpose. Immigration cases through USCIS require AABB-accredited, chain-of-custody testing with results sent directly to the requesting agency or embassy. Tell us it is for immigration when you call so we set up the case the right way from the start.
What is the difference between a legal and a personal DNA test?
The science and accuracy are identical. The difference is the collection protocol. A legal test verifies identities and documents chain of custody so the results can be used in court or by an agency. A personal test is collected without that documentation and is for your own knowledge only, so it cannot be used legally.
