What’s the difference between an accredited and an unaccredited laboratory?

In this article, we discuss the main differences between accredited and unaccredited testing laboratories.

Read the full article, below.

What does it mean if a laboratory is accredited?

An accredited laboratory has been independently checked and approved to meet strict national and international quality standards.

Laboratory accreditation involves assessment against recognised standards such as ISO/IEC 17025, which sets out the requirements for testing and calibration laboratories. Accreditation is granted by an internationally recognised accreditation body following a rigorous and impartial evaluation process.

To become accredited, a laboratory must prove that:

• Its equipment is properly maintained and calibrated
• Testing methods are scientifically valid and consistently applied
• Staff are trained and competent
• Results are accurate, traceable and repeatable
• Quality systems are independently reviewed and audited regularly

Accreditation confirms that the laboratory operates to a consistently high standard and that its results can be relied upon with confidence.

What is an unaccredited laboratory?

An unaccredited laboratory has not been independently assessed by a recognised accreditation body.

This doesn’t necessarily mean it produces inaccurate results – but there’s no external verification of its methods, staff training, or equipment. That means customers must rely on the company’s own claims about accuracy and quality.

Unaccredited labs are more common among companies offering peace-of-mind or low-cost testing, where results are for personal use only and not intended for court or official purposes.

AlphaBiolabs is ISO 17025-accredited for peace of mind, at-home testing, and legal testing for court and other official matters. 

Why does accreditation matter?

Accreditation matters because it gives you confidence that your test results are trustworthy and produced under strict quality controls.

It’s especially important if your test results will be used in court or for any other official purpose, where only results from accredited laboratories are accepted.

Choosing an accredited laboratory means:

• Accurate, reliable results – tested under audited conditions
• Recognised standards – accepted by courts and government agencies
• Independent oversight – processes regularly reviewed by experts
• Clear traceability – from sample collection to reporting

Do I need an accredited laboratory for a peace of mind test?

While accreditation isn’t essential for a laboratory offering peace of mind DNA, drug or alcohol testing (for personal knowledge only), using an accredited laboratory gives added reassurance that the laboratory tests are carried out to professional standards – the same standards required for a legal test for court.

How can I check if a laboratory is accredited?

It’s easy to check whether a testing laboratory is accredited:

• Look for accreditation logos and the accreditation number on the company’s website or test reports.
• Visit the IAF CertSearch website (International Accreditation Forum database) and search for the company name to view its accreditations.
