Informational (Non-Legal) DNA Test
Peace of Mind DNA Testing — Your Way
Want answers without the formalities? Our informational DNA test confirms biological relationships strictly for your personal knowledge — no court involvement, no legal paperwork.
You have two options:
Do It Yourself: Order an at-home kit and collect samples on your own time, in your own space. Simple instructions included — just swab, seal, and mail it back. Results arrive within 2 business days.
Let Us Handle It: Schedule an appointment at one of our office locations or have us come to you. We'll collect the samples so you don't have to worry about a thing.
The science is the same as legal testing — accurate and reliable. These results are simply for your peace of mind and personal confirmation only, not for court or official use.

Can I get a DNA test if the other parent refuses to participate?
Yes. LaRoc Precision Testing offers "motherless" and single-party testing options. In some cases, other biological relatives such as grandparents, siblings, or aunts and uncles can be tested as an alternative. Contact us at 843-543-2533 or visit LPTSC.com to discuss the best option for your situation.
Is a DNA test from LaRoc Precision Testing accepted in South Carolina courts?
Yes. We offer court-admissible DNA testing that follows strict chain-of-custody protocols required by South Carolina courts. Our legal DNA tests are accepted for paternity establishment, child support, custody proceedings, and other legal matters.
Call or text 843-543-2533 or book at LPTSC.com to schedule your legal DNA test.
How long does it take to get DNA test results?
Results for most DNA paternity tests are returned within 3–5 business days from the time all samples are collected and received by the lab. Expedited processing may be available depending on your circumstances.
Contact us at 843-543-2533 or visit LPTSC.com for details.
What is the difference between a legal and a non-legal DNA test?
A non-legal DNA test is for personal peace of mind. It is private, affordable, and fast, but cannot be submitted to a court. A legal or court-admissible DNA test follows a strict chain-of-custody process — meaning all parties are verified and samples are properly documented — making the results valid for use in SC courts, child support agencies, and immigration cases.
LaRoc Precision Testing offers both. Call 843-543-2533 or visit LPTSC.com to find out which one is right for your situation.
Do you offer mobile DNA testing near me?
Yes. LaRoc Precision Testing is a mobile DNA testing service based in North Charleston, SC. We come to you, at your home, office, or another agreed-upon location. We offer mobile testing Monday through Friday from 6:30–9pm and are available on weekends as well.
We serve 11 counties across South Carolina's Lowcountry. Book at LPTSC.com or call or text 843-543-2533.
Can a DNA test be used for child support cases in South Carolina?
Yes. A court-admissible DNA paternity test from LaRoc Precision Testing can be used to establish paternity for child support proceedings in South Carolina. Our tests follow the chain-of-custody requirements needed for submission to the SC Department of Social Services and family courts. Call or text 843-543-2533 or visit LPTSC.com to get started.
What do I need to bring to my DNA testing appointment?
You will need to bring a valid government-issued photo ID such as a driver's license, state ID, or passport. For minors being tested, a parent or legal guardian must be present and provide their own valid ID. No other preparation is required — we handle everything else. Call 843-543-2533 or visit LPTSC.com if you have questions before your appointment.
Do you offer DNA testing on evenings and weekends?
Yes. We know that life does not always fit into a 9-to-5 schedule. LaRoc Precision Testing offers mobile DNA and drug testing Monday through Friday from 6:30–9pm and is available on weekends. Our North Charleston location also accepts scheduled appointments.
Book online at LPTSC.com or call or text 843-543-2533.
How much does a paternity test cost in South Carolina?
Pricing varies depending on whether you need a non-legal (personal) test or a legal court-admissible test, and the number of parties being tested. LaRoc Precision Testing offers competitive, transparent pricing with no hidden fees. Visit LPTSC.com or call or text 843-543-2533 for current pricing and to find the right test for your needs.
Can a grandmother or other relative be tested instead of the father?
Yes. When the alleged father is unavailable, unwilling, or deceased, we can test biological relatives such as the paternal grandmother, grandfather, sibling, aunt, or uncle to help establish a biological connection. This is called kinship or family relationship testing.
Call or text 843-543-2533 or visit LPTSC.com to discuss your specific situation and which test is recommended.
