Paternity Lab is one of the more genuinely strong partners we cover on this site — more than 20 years in operation, AABB accreditation, and a track record that’s held up against independent verification. As covered in our At-Home vs. Legal Paternity Tests guide, accreditation is the thing that actually matters when choosing a testing provider, and this is where Paternity Lab’s case is strongest.
AABB Accreditation: Why It Matters
AABB (originally the American Association of Blood Banks, now operating more broadly as an accrediting body) accreditation for DNA relationship testing means a lab has passed a rigorous, independently audited standard for testing procedures, chain-of-custody protocols, and result accuracy. This is the credential that matters most when evaluating a paternity testing provider — it’s the difference between a lab whose legal-test results will actually be accepted by courts and government agencies, and one whose results might not be. Paternity Lab holds this accreditation, which is a real, verifiable credential rather than a marketing claim.
Accuracy: 99.99% and Independently Verified
Paternity Lab reports 99.99% accuracy for confirming paternity, which is standard for accredited labs using modern STR marker analysis — and in research for this review, that figure held up against independent comparison to hospital-lab testing, rather than being an unverified in-house claim. Combined with the AABB accreditation, this is a genuinely trustworthy accuracy profile, not a number worth taking on faith alone.
Chain of Custody, Done Properly
For legal testing specifically, Paternity Lab follows a strict, documented chain-of-custody process: neutral third-party sample collection, verified photo ID for all parties, and documentation built to withstand legal scrutiny — exactly the procedural rigor that separates a legal-admissible result from an at-home one, as explained in our format-comparison guide. If you need a result that will hold up in a custody case, child support proceeding, or immigration petition, this is the process that makes that possible.
Turnaround and Testing Options
Paternity Lab offers both at-home (“peace of mind”) and legal testing formats, along with more specialized tests including prenatal and immigration DNA testing. Standard turnaround for results is typically within a few business days of the lab receiving samples, which is competitive within the category — though exact timing can vary by test type and current lab volume, so confirm current turnaround estimates directly when ordering.
Where We Didn’t Find Real Caveats
In the interest of being consistently honest across this site rather than manufacturing a caveat where none was found: our research didn’t turn up significant, credible complaints about Paternity Lab’s accuracy, accreditation, or process integrity. That’s worth stating directly rather than padding this review with an artificial “on the other hand” to seem balanced — some partners genuinely have fewer real weaknesses than others, and manufacturing criticism for its own sake would be its own kind of dishonesty.

Frequently Asked Questions
Is Paternity Lab’s at-home test the same lab process as their legal test?
Yes — as covered in our format-comparison guide, the underlying DNA analysis is identical between formats. The difference is entirely in sample collection procedure and documentation, not lab methodology.
Can Paternity Lab test be used for immigration purposes?
Yes — Paternity Lab offers immigration-specific DNA testing that follows the documentation requirements government agencies require for these petitions, which is distinct from both standard at-home and standard legal testing in its specific procedural requirements.
What if the test result is disputed by the other party?
This is exactly why legal (not at-home) testing matters if there’s any chance of dispute — the documented chain of custody is what allows a legal result to stand up to a challenge in a way an at-home result can’t.
