What People Know vs. What They Should Know About Laboratory Reference Ranges
Bibliographic record
Abstract
Laboratory test results are increasingly available to health consumers. Almost all test results are accompanied by a reference range to aid in interpretation. This study asked 25 non-healthcare providers to explain the term reference range. The descriptions highlighted four principal themes: health consumers were unsure about their understanding of the term reference range; they equated a reference range with a normal range; few had some degree of awareness of the limitations of reference ranges; and few had limited awareness of the difference between a reference range and clinical cutoff. Further efforts should be made to educate health consumers on the utility and limitations of reference ranges. When providing results to health consumers, laboratories should consider including other means of contextualizing test results in order to support their understanding of potential clinical significance.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
