Reference Materials and Process Analysis rolled into one

Global Proficiency Charts

One of the most important quality controls in a laboratory is the internal quality control. By using an internal quality control, the analyst checks if his or her activities comply with the requirements. An effective and widely used way to apply the internal quality control is the use of microbiological reference material. 

Shewhart ChartThe results of the analysed reference materials are generally plotted on a Control Chart. The Control Chart shows whether the process is stable or unstable. This refers to the signal value, when there is a variation which is generated by special causes and situations. Each accredited laboratory has a Control Chart for each individual test. In cases of uncontrolled quality, a corrective action must be taken and documented. The individual chart provides information about the average and the standard deviation of the results of investigation.

BiosistoChart is an application for recording and capturing results of primary controls. Here, the NEN 6603 standard is leading to record and monitor the performance of the analytical methods. It is possible to compare all your company locations in one Control Chart and in a Box & Interval plot graph.  Another possibility is to compare your results (anonymously) with other companies who use the same microbiological reference material from Biosisto. Proficiency testing  by means of interlaboratory comparisons is made possible by transformation and interpretation of the internal quality control data.

How it works
