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

The main difference between an accredited and an unaccredited laboratory is that an accredited laboratory has been independently assessed to meet recognised quality and technical standards, while an unaccredited laboratory has not.

Accredited labs follow strict procedures to ensure accurate, reliable, and traceable test results. This independent oversight is especially important for legal or court-approved testing, where only accredited laboratories – like AlphaBiolabs, which holds multiple UKAS accreditations and Ministry of Justice approval – can provide results that are officially recognised.

In this article, we explore the importance of accreditation in more detail.

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.

In the UK, laboratory accreditation is carried out by the United Kingdom Accreditation Service (UKAS) – the government-appointed body responsible for assessing laboratories against recognised standards, such as ISO/IEC 17025, which sets out the requirements for testing and calibration laboratories.

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

Once accreditation is granted, the laboratory is added to the official UKAS directory, which anyone can check online.

What is an unaccredited laboratory?

An unaccredited laboratory has not been independently assessed by UKAS.

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 UKAS 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 UK courts and government agencies
• Independent oversight – processes regularly reviewed by experts
• Clear traceability – from sample collection to reporting

What accreditations does AlphaBiolabs hold?

AlphaBiolabs holds several accreditations that demonstrate our technical competence and commitment to quality.

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 the UKAS logo and accreditation number on the company’s website or test reports.
• Visit the UKAS website and search for the company name to occur its accreditations.

AlphaBiolabs’ UKAS accreditations are available to view on the UKAS website.

You can also view a full list of our accreditations, certifications and professional memberships on our Accreditations page.
