Using The Qc Programs; Introduction - Mindray BC-2800 Operator's Manual

8.1 Introduction

Quality Control (QC) consists of strategies and procedures that measure the precision and
stability of the analyzer. The results imply the reliability of the sample results. QC involves
measuring materials with known, stable characteristics at frequent intervals. Analysis of the
results with statistical methods allows the inference that sample results are reliable.
Mindray recommends you run the QC program daily. A new lot of controls should be
analyzed in parallel with the current lot prior to their expiration dates. This may be
accomplished by running the new lot of controls twice a day for five days using any empty QC
files. The QC files calculate the mean, standard deviation and coefficient of variation for each
selected parameter. The instrument-calculated means of these ten runs should be within the
expected ranges published by the manufacturer.
This analyzer provides two QC programs – QC with controls and X-B analysis.
Samples, controls, calibrator and waste are potentially infectious. Wear
proper personal protective equipment (e.g. gloves, lab coat, etc.) and follow
safe laboratory procedures when handling them in the laboratory.
Use the specified controls. Using controls other than the specified will lead
to misleading results.
Refer to the instructions of use of the controls for how to store and use the
controls.
