Abstract: An automated biological specimen screener (500) reports an assessment of slide and specimen preparation and quality. The automated biological specimen screener (500) measures parameters which reflect slide physical characteristics, specimen collection quality, and specimen preparation quality. The automated system (500) reports an objective measure and uses a consistent standard of evaluation (118, 120, 122, 124, 126). The automated system (500) evaluates characteristics of a slide set from a clinic (103). The automated system (500) makes a determination of whether these characteristics are within a training capability of a given automated biological screener.  Additionally, rather than periodic reviews, slides (201) successfully scanned by the automated system (500) may be used as part of a specimen preparation assessment (90, 100).
