Recommendations for the Use of Liquid Chromatography-Mass Spectrometry in the Clinical Laboratory: Part I. Implementation and Management
Bibliographic record
Abstract
Many types of assays involving mass spectrometry have been developed and applied in clinics. However, mass spectrometry has not been widely implemented yet relative to other measurement methods, including biochemical assays, immunoassays, and molecular diagnostics. Despite its strong advantage as an analytical method, many laboratory physicians and clinical laboratories are unwilling to introduce it. Fundamental elements, such as instruments, reagents, facilities, skilled human resources are required to implement mass spectrometry. This review contains considerations for the introduction of liquid chromatography-mass spectrometry to support the clinical laboratories interested in or planning to implement mass spectrometry.

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.
