BIOSPECIMEN PROFICIENCY TESTING

We provide a Proficiency Testing (PT) programme to laboratories working with biospecimens, including biorepositories, clinical laboratories, research organisations and bioservice providers. Our research focus on biospecimen science, our dedication to quality and our range of in-house services make us an ideal partner for PT. Our PT programme is endorsed by the International Society for Biological and Environmental Repositories (ISBER).

Validate your routine lab methods

The PT programme provides an external quality assessment tool to verify the precision and accuracy of your biospecimen testing methods, and the efficiency of your processing methods.

Compare your performance to others

The principle of performance benchmarking applied in our PT programme means that your results will be compared to those of other laboratories, from different sectors all over the world.

Comply with certification & accreditation requirements

Proficiency testing offers organisations that are seeking compliance with ISO 20387, ISO 17025, ISO 15189, CLIA, CAP or equivalent, the opportunity to fulfill the respective normative requirements.

Gain more credibility & visibility

By participating in our PT programme you can assure customers, collaborators, funding agencies and regulatory bodies of the validity of your results. This can help build your reputation for high quality laboratory methods and gain international visibility. 

 

Improve performance & prove consistency

The assessment of your laboratory’s proficiency allows you to monitor and improve performance by identifying potential problems and providing additional motivation. Regular participation in our PT programme will also prove consistency of performance over time. 

How does it work?

Our PT programme works as an external quality assessment tool that lets you verify and benchmark the performance of your biospecimen processing or testing methods through the following steps:

What do you receive?

In the end, each participant receives:

  • a personalised report
  • a certificate of participation
  • a label of participation
