OBJECTIVES: Validation of the Architect 25-OH vitamin D assay. DESIGN AND METHODS: Determination of repeatability, reproducibility, accuracy profile and 25(OH)-vitamin D2 recovery on native samples. Comparison with DiaSorin Liaison and RIA. RESULTS AND CONCLUSION: Coefficients of variation: <6% (13.6ng/mL) and 2.2% (78.1ng/mL). Functional sensitivity: 5ng/mL. Accuracy profile shows that the method is validated between 13.6 and 78.1ng/mL. Recovery of 25(OH)D2: 75,8%( 95% CI: 61.9-89.7%). Good correlation with DiaSorin RIA and Liaison <50ng/mL; above this threshold a systematic positive bias was observed.
