Measurement

Reproduzierbarkeit

Definition

Die Übereinstimmung zwischen unabhängigen Messergebnissen, die unter veränderten Bedingungen (z. B. unterschiedliche Bediener, Instrumente, Laboratorien oder Zeiträume) erzielt wurden.

Erklärung

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.
