PHARMATEK · Fonction rénale
Calculateur du taux de réduction de l’urée (TRU)
Calculer le pourcentage brut du TRU à partir de concentrations pré- et post-dialyse vérifiées provenant de la même séance, avec une identité partagée d’azote uréique ou d’urée entière.

- Version de la méthode
- Raw urea reduction ratio arithmetic v1: URR (%) = ((predialysis concentration - postdialysis concentration) / predialysis concentration) × 100; both values must use one explicit shared analyte/unit identity, either BUN in mg/dL or whole urea in mmol/L; NIST normalization uses nitrogen atomic weight 14.0067, so 1 mg/dL BUN = 10 / (2 × 14.0067) mmol/L whole urea and 1 mmol/L whole urea = 2.80134 mg/dL BUN; postdialysis concentration must be less than or equal to predialysis concentration
- Population
- People with verified predialysis and postdialysis BUN or whole-urea concentrations obtained from one completed hemodialysis session, with an independently documented and applied standardized pre/post sampling protocol covering collection timing, access technique, access and cardiopulmonary recirculation, and remote-compartment rebound handling. Both results must use one shared analyte/unit identity; the analyte, units, source results, session pairing, and sampling context must be verified; and the postdialysis concentration must be less than or equal to the predialysis concentration.
- Limites et exclusions
- Any dialysis adequacy target, cutoff, threshold, category, adequacy determination or claim; Kt/V calculation or inference; dialysis prescription; diagnosis, prognosis, management, treatment, or any other clinical decision. · Predialysis and postdialysis results from mismatched hemodialysis sessions; incomplete or unverified session pairing; nonstandardized, undocumented, or unverified sampling timing, access technique, recirculation, or rebound context; sample dilution; or unverified analyte, unit, assay, or source-result identities. · Mismatched units or analyte identities, including mixing BUN mg/dL with whole urea mmol/L without explicit quantity normalization; inferred or silently reinterpreted units; or a postdialysis concentration greater than the predialysis concentration, for which negative URR output is inapplicable.
