Reproducibility of blood lead levels after blood stored for seven days in trumpeter swans (Cygnus buccinator) and mute swans (Cygnus olor)
Bibliographic record
Abstract
Wild animals, particularly birds, often present with clinical signs of lead toxicosis when admitted to wildlife rehabilitation centers. Many wildlife rehabilitators and wildlife biologists do not have a point-of-care blood lead level analyzer, nor do they always have the financial resources to submit samples for external laboratory analyses. Often there is a delay between taking a blood sample in the field and subsequent analysis. The objective of this study was to determine whether a delay in processing a blood sample for lead testing would significantly alter the blood lead level results in swans. Whole blood samples were collected from 49 trumpeter swans and four mute swans and placed in ethylenediaminetetraacetic acid (EDTA) blood collection tubes. Samples were run on a LeadCare II analyzer at day 0, stored at 4°C for 7 days, and rerun on day 7. Results indicate that whole blood can be stored in EDTA blood collection tubes for up to seven days at 4°C while maintaining reproducibility in blood lead level results that were analyzed from a point-of-care blood lead level system.

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.
