Apparent Elevated Creatinine After Ingestion of Nitromethane: Interference With the Jaffe reaction
Bibliographic record
Abstract
We assessed a 2-year 4-month-old boy found to have a persistently elevated serum creatinine (peak 926 μmol/L) as measured by the Jaffe reaction after ingesting an unknown quantity of fuel for a model car, which commonly contains nitromethane. The patient was otherwise clinically well and the remaining investigations were unremarkable. When creatinine concentrations were measured with specific enzymatic testing on these same blood samples, all values were within normal limits. Nitromethane has been shown to interfere with the determination of serum creatinine through the Jaffe reaction. Because many ingestions present only rarely, it is not possible for the emergency department clinician to be aware of all toxin factors affecting patient management. This case illustrates the importance of analysis of laboratory results in the context of the patient's clinical status.

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.
