What is the difference between SAMHSA-certified and AABB-accredited?
If you've spent any time researching drug testing or DNA testing, you've probably come across phrases like "SAMHSA certified" or "AABB accreditation" more than once. Most people see those terms and wonder if they're supposed to know what they mean. The confusing part is that both certifications sound very official, but they apply to different types of testing.
SAMHSA is tied to drug testing. AABB is tied to DNA testing. That's really it.

What is SAMHSA?
Let's start with the one people search for the most: SAMHSA.
What does SAMHSA stand for?
SAMHSA stands for the Substance Abuse and Mental Health Services Administration. It's part of the U.S. Department of Health and Human Services and helps oversee programs related to substance use, mental health, and workplace drug testing standards.
Most people come across SAMHSA while researching workplace drug testing or DOT drug testing requirements. SAMHSA helps establish federal guidelines for how drug testing should be performed.
When companies mention using SAMHSA-certified labs, they're referring to laboratories that meet strict federal standards for drug testing accuracy and procedures.
That includes rules around:
-
Specimen collection
-
Chain of custody
-
Laboratory security
-
Reporting procedures
-
Quality control
-
Drug testing accuracy
The goal is pretty simple: reduce mistakes and make sure the testing process is handled properly from beginning to end.
SAMHSA-certified labs are a big deal for workplace and regulated testing, where the drug test results may influence:
-
Employment
-
DOT compliance
-
Workplace safety
-
Professional licensing
-
Legal disputes
Remember, not every lab meets professional testing standards. Always choose SAMHSA-certified or AABB-accredited labs. Health Street's employee drug testing services work with SAMHSA-certified labs that follow federally recognized testing standards.
What is SAMHSA certification?
It basically means a laboratory has been approved under federal workplace drug testing guidelines. Not every lab can claim they're SAMHSA certified. Laboratories have to go through inspections, proficiency testing, and ongoing monitoring to maintain certification status.
For employers, drug testing should never be performed outside of SAMHSA-certified labs. Failing to use a SAMHSA-certified lab can lead an employer to make a hiring decision based on a drug test that wasn't handled correctly, or a sample getting mixed up because proper chain of custody procedures weren't followed.
SAMHSA-certified labs exist to prevent these kinds of errors. The certification helps create consistency across the testing process so employers, employees, and government agencies know the procedures are being handled properly.
This is especially important for:
-
Federal workplace testing
-
Transportation industries
-
Aviation
-
Healthcare positions
-
Safety-sensitive jobs
What is AABB accreditation?
Now let's talk about AABB. Unlike SAMHSA, AABB is not a federal government agency.
AABB stands for Association for the Advancement of Blood & Biotherapies. While that name sounds very medical, many people encounter AABB accreditation while researching DNA testing.
Most people come across AABB accreditation while researching:
-
Legal paternity testing
-
Immigration DNA testing
-
Court-admissible DNA testing
-
Relationship DNA testing
When someone needs DNA test results for legal purposes, courts and government agencies usually require the testing to be performed through AABB accredited labs. Legal DNA testing accredited by AABB has stricter requirements than the at-home DNA kits people buy online.
For example, if someone buys a personal DNA kit online and performs the test at home, the process is too inconsistent and informal. The DNA sample could be compromised or contaminated. If someone needs DNA results for child custody, immigration, or legal documentation, the testing process must follow strict identity verification and chain-of-custody procedures. That's where AABB DNA testing accreditation becomes important.
Health Street offers DNA testing services and legal paternity testing through AABB accredited DNA testing labs that meet those standards.
Why AABB accreditation matters for DNA testing
A lot of people don't realize there's a major difference between informational DNA testing and legal DNA testing. An informational test is usually for personal knowledge. A legal DNA test is meant to hold up in court or satisfy government requirements.
AABB accredited labs follow strict procedures designed to protect the integrity of the testing process, including:
-
Identity verification
-
Chain of custody documentation
-
Controlled specimen collection
-
Laboratory quality standards
-
Secure reporting procedures
Without those steps, DNA results may not be accepted by courts or government agencies.
So what's the actual difference?
Honestly, the easiest way to remember it is this:
-
SAMHSA certified labs are used for drug testing
-
AABB accredited labs are used for DNA testing
That's the simplest explanation.
Both certifications focus on accuracy and proper procedures, but they apply to completely different industries and testing situations. If someone needs federally compliant workplace drug testing, SAMHSA matters. If someone needs legally recognized DNA testing, AABB matters.
Sometimes companies work with both types of laboratories, depending on the services being offered.
Why testing standards matter so much
A lot of people don't think much about laboratory certifications, but these standards exist for a reason.
Without these standards:
-
A drug test gets mishandled
-
A sample gets contaminated
-
DNA results aren't accepted in court
-
Chain of custody paperwork is incomplete
-
A testing provider cuts corners
Those situations can create serious legal and professional problems. Working with providers connected to SAMHSA certified labs or AABB accredited DNA testing labs can make such a big difference.
These certifications help improve:
-
Testing accuracy
-
Reliability
-
Documentation
-
Compliance
-
Quality control
And at the end of the day, people simply want to trust the results they're receiving.
Frequently Asked Questions
Can a drug test still be inaccurate if a lab is certified?
While no testing process is completely error-proof, certified laboratories follow strict procedures designed to reduce the risk of sample mix-ups, contamination, reporting errors, and improper handling. These standards help improve consistency and reliability throughout the testing process.
Why is chain of custody important during testing?
Chain of custody documents who handled the sample at every stage of the testing process, from collection to final reporting. This helps protect the integrity of the sample and can become especially important for legal disputes, workplace compliance, and court-admissible testing.
Are certified testing standards important for small businesses too?
Yes. Small businesses can face the same legal, hiring, and compliance risks as larger employers if testing procedures are not handled correctly. Using properly accredited or certified laboratories helps reduce these liability concerns.
