Detection of the Administration of Human Erythropoietin (HuEPO) to Canines
Bibliographic record
Abstract
Recombinant human erythropoietin (rHuEPO) doping is prohibited in animal (canine and equine) sport. The effectiveness of a range of immunoassay screening methods for the detection of rHuEPO in canine urine was evaluated. The excretion profiles following rHuEPO administration to dogs were investigated. The presence of rHuEPO in postadministration samples was confirmed using the World Anti-Doping Agency (WADA)-approved isoelectric focusing immunoblotting confirmatory technique. Following the administration study, a screening program involving approximately 6000 greyhound sport (mostly racing) samples was undertaken for rHuEPO. This resulted in the detection of the first rHuEPO positives in the world of canine or equine sport. In an additional case, endogenous HuEPO was detected in a sample submitted as greyhound urine. It was determined that this arose from the submission to control stewards, as greyhound urine, of a substance that was, in fact, human urine. This was a particularly welcome development as definitive confirmatory evidence of such sample switching can be difficult to obtain in the case of greyhounds.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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 teacher head, not a consensus.
