Measurement

Reproductibilité

Définition

La concordance entre des résultats de mesure indépendants obtenus dans des conditions différentes, telles que différents opérateurs, instruments, laboratoires ou périodes.

Explication

A mass spectrometry method is reproducible if three different laboratories analyzing the same blood sample all report a glucose concentration within 2% of each other. Reproducibility is broader than repeatability (same conditions): a weight measured to ±0.01 g by the same operator on the same day may have reproducibility of only ±0.05 g across laboratories due to instrument-to-instrument variation.
