Evolution of an External Quality Assessment Program in Canadian Mycobacteriology Laboratories Three Years of Proficiency Testing Data
Bibliographic record
Abstract
In 2000, the Canadian mycobacteriology proficiency testing program was updated and expanded to improve proficiency and standardize the main activities and testing performed in Canadian clinical mycobacteriology laboratories. The program was divided into 2 phases and included samples for acid-fast microscopy, species identification, susceptibility testing for Mycobacterium tuberculosis and nontuberculous mycobacteria, nucleic acid amplification for the detection of M tuberculosis complex in clinical samples, and restriction fragment length polymorphism (RFLP) typing of M tuberculosis. Results of participating laboratories are given for a 3-year period (2000–2002). Canadian laboratories exhibited a high level of proficiency in both phases of the program. Improvements were demonstrated in susceptibility testing of M tuberculosis, and standardization was achieved with Mycobacterium avium complex susceptibility testing. Laboratories demonstrated proficiency in determining unique and identical strains of M tuberculosis using RFLP; however, difficulties occurred with interlaboratory reproducibility.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
