CAP, consensus of 80% participants from the College of American Pathologists; most frequent value, using criteria based on the results of 25 years of external quality assessment in Austria [6]; and OMIS, using criteria from external proficiency testing carried out in Europe in 1997 [5].

Abbreviations: CAP, College of American Pathologists; OMIS, Overall Misclassification Index Score.

All grades of unacceptable results from under-performing institutes were consistently higher or lower as compared to the acceptable results obtained from compliant laboratories.
