Testing You Can Trust
If you're considering DNA testing, one of the first questions you'll need to answer is whether you need Legal DNA Testing or Peace-of-Mind DNA Testing.
Many people assume all DNA tests are the same. While the laboratory science behind the testing is virtually identical, the collection process and how the results can be used are very different.
Choosing the wrong type of test can lead to frustration, additional costs, and delays—especially if legal action becomes necessary later.
At Veritas Mobile Diagnostics, we help clients throughout Tulsa Metro and Northeastern Oklahoma understand their options so they can select the testing solution that best fits their needs.
The Good News: Both Tests Are Highly Accurate
Let's start with one important fact:
Whether you choose Legal DNA Testing or Peace-of-Mind Testing, the laboratory analysis itself is highly accurate.
In most paternity cases:
Inclusion results typically exceed 99.99% probability of paternity.
Exclusion results can determine with near certainty that an individual is not the biological parent.
The difference is not the science.
The difference is the documentation and collection process.
What Is Peace-of-Mind DNA Testing?
Peace-of-Mind DNA Testing, sometimes called informational testing, is designed for individuals who simply want answers for personal knowledge.
Common reasons people choose Peace-of-Mind Testing include:
Personal curiosity
Family questions
Relationship confirmation
Private reassurance
Informal family discussions
The results provide valuable information, but they are intended for personal use only.
Advantages of Peace-of-Mind Testing
✔ Lower cost
✔ Simple collection process
✔ Fast scheduling
✔ Confidential results
✔ Personal answers without legal requirements
For many families, this is exactly what they need.
What Is Legal DNA Testing?
Legal DNA Testing follows a strict chain-of-custody process designed to verify participant identities and protect the integrity of the results.
Because every step is documented, legal DNA test results may be used in official proceedings.
Common Uses for Legal DNA Testing
Legal DNA testing may be required for:
Child support cases
Custody disputes
Court proceedings
Immigration matters
Inheritance and probate cases
Birth certificate amendments
Social Security benefits
Tribal enrollment documentation
Adoption-related matters
If a judge, attorney, government agency, or immigration office will review the results, legal testing is usually required.
What Is Chain of Custody?
Chain of custody is the process that documents:
Who provided the sample
When the sample was collected
Who collected the sample
How the sample was handled
When the laboratory received the sample
This documentation helps ensure that the samples tested belong to the individuals identified in the report.
Without chain-of-custody procedures, there is no independent way to verify who actually provided the samples.
That is why Peace-of-Mind results generally cannot be used in court.
Why Legal DNA Testing Costs More
Many clients notice that Legal DNA Testing is typically more expensive than Peace-of-Mind Testing.
The additional cost reflects:
Identity verification
Collection documentation
Chain-of-custody procedures
Court-admissible reporting
Additional administrative requirements
While the laboratory testing itself may be similar, the legal documentation requirements add value and credibility to the final report.
A Common Mistake People Make
One of the most common mistakes occurs when someone chooses Peace-of-Mind Testing because it costs less, only to discover later that they need the results for court.
Unfortunately, the original test often cannot be converted into a legal test after the fact.
This means participants may need to:
Schedule a new appointment
Submit new samples
Pay for testing again
Wait for new results
Ask Yourself This Question First
Before scheduling a DNA test, ask:
"Could these results ever be used for a legal purpose?"
If the answer is even "maybe," Legal DNA Testing is often the safest choice.
Which Test Is Right for You?
Choose Peace-of-Mind Testing If:
You only want personal answers.
No court or government agency is involved.
The results are for private use.
You do not anticipate future legal proceedings.
Choose Legal DNA Testing If:
An attorney is involved.
A court case exists or may arise.
Child support is being established.
Custody is being disputed.
Immigration documentation is required.
Government agencies require proof of relationship.
When in doubt, ask your testing provider before scheduling.

The Bottom Line
Both Legal DNA Testing and Peace-of-Mind Testing offer highly accurate answers regarding biological relationships.
The key difference is how the samples are collected, documented, and whether the results can be used for legal purposes.
If you're simply seeking personal answers, Peace-of-Mind Testing may be the right choice.
If there's any possibility that the results will be needed for court, child support, custody, immigration, or other official purposes, Legal DNA Testing is the better option.
