Updates - Proficiency Testing


Acceptance Limits

CALA continues to review the acceptance limits of our proficiency testing to ensure they remain fit-for-purpose.  This involves input from technical experts and regulators as well as a review of acceptance limits from other proficiency testing providers.  By the end of 2018, we are anticipating the completion of a review of the acceptance limits for all analytes in the CALA Proficiency Testing program.

New Test Groups

The expressed interest in our new test groups has been better than expected.  We will now be offering proficiency testing in the following three new test groups:

     Solids in soil

     • Nutrients in soil

     • Anions in soil

In response to this, for our January study, we will be shipping over thirty sample sets for each of those test groups.  They will each consist of two samples. If the data looks favourable, we will increase the number of samples per set to four, consistent with most of the CALA proficiency testing schemes.


Subcontractors

CALA is pleased to announce we have finalized contracts with four organizations for the ongoing production, characterization and shipping of proficiency testing samples for the CALA program.  Environment and Climate Change Canada will continue to produce most of the CALA proficiency testing samples. The other subcontractors include:

• Thomas Pang for asbestos

• Clinical Microbiology Proficiency Testing (CMPT) based out of Vancouver, will be preparing the water microbiology samples

• Phenova will be preparing some of the pesticides samples, oil and grease and hexavalent chromium.

These contracts will ensure a stable fee structure for the next four years.  Specific details about the subcontractors and the test groups that they are responsible for, can be found at here.
