Version de la méthode: Measured total-calcium × inorganic-phosphate arithmetic v1: raw conventional product (mg²/dL²) = measured total calcium (mg/dL) × measured inorganic phosphorus mass (mg/dL); raw SI product (mmol²/L²) = measured total calcium (mmol/L) × measured inorganic phosphate (mmol/L); an inorganic-phosphate result in mg/dL explicitly identifies elemental-phosphorus mass, while mmol/L identifies amount concentration with one phosphorus atom per phosphate moiety; NIST nominal atomic weights 40.078 for calcium and 30.973761998 for phosphorus give 1 mg/dL calcium = (10 / 40.078) mmol/L, 1 mg/dL phosphorus = (10 / 30.973761998) mmol/L, and 1 mg²/dL² = [100 / (40.078 × 30.973761998)] mmol²/L²; outputs remain raw and unrounded. KDIGO 2017 describes the product as a mathematical construct and advises evaluating individual calcium and phosphate values together rather than using the product to guide CKD clinical practice
Population: People with contemporaneous quantitative measured total-calcium and measured inorganic-phosphate/phosphorus results from the same serum or plasma specimen and a compatible laboratory and clinical context, after verifying collection timing, specimen identity, the measured-total-calcium and inorganic-phosphate-as-phosphorus analyte identities, assay identities, reported units, and both source results.
Limites et exclusions: Measurements from different collection times or specimens, incompatible laboratory or clinical contexts or assays, mismatched data, or unverified collection timing, specimen, analyte, assay, unit, or source-result identities. · Albumin-corrected, adjusted, calculated, or ionized calcium in place of measured total calcium; whole-phosphate or phosphate-salt mass in place of elemental-phosphorus mass for mg/dL input; inferred identities or units; or substitution or derivation of a missing result. · Any target, cutoff, threshold, reference range, result category, calcification-risk statement, diagnostic classification, diagnosis, prognosis, dialysis-management recommendation, treatment, management, or other clinical decision.
