Digital Interpretive Proficiency Testing
CADQAS provides expertise, services and infrastructure to support the adoption of regional testing for selected IHC markers in tissue-based pathology worldwide.
NEW for 2025
Following feedback, we have made changes to our programme and it now consists of three parts:
Education Session:
We will hold live education sessions before each proficiency test opens.
These sessions will provide updates, guidance and practical approaches to interpretation of the relevant biomarker.
Some biomarkers (PRAME, P53 & P16) just have an extended educational session, with no separate proficiency test. Instead, there will be live, interactive scoring of cases and online polls.
Proficiency Test:
Each of our proficiency test modules contain a maximum of 6 cases and will be open for 12 days.
Once each test has closed, and ahead of the live case review session, you will receive information on how your scores compare with others.
Case Review Session:
After each proficiency test closes, we will hold a live, interactive review of the relevant cases.
All live sessions will be recorded and then hosted on our YouTube channel. Please subscribe so you don’t miss any updates!
Certificates of participation will be available upon completion of feedback forms.
