Problems solved by technology

Dealing with this amount of quality controls (especially in a timely manner) can be quite complex
In particular, it can be expensive to prepare (including e.g. freeze-dry) many different types of quality control preparations
Additionally, manual reconstitution of quality controls prior to use can be quite time-consuming, tedious, and error-prone

Abstract

In one aspect of the present invention, a method for monitoring the performance of an analyzer with an automatic preparation device for a biological sample, comprising: receiving an instruction to perform a monitoring program; after receiving an instruction to perform a monitoring program: by The automated preparation device obtains at least two quality control components from a repository comprising a plurality of quality control components, and mixes the at least two quality control components in a sample preparation container by the automated preparation device to obtain a simulated A quality control characteristic of the biological sample to be analyzed by the analyzer, the method further comprising determining at least one parameter of the quality control, and determining a state of the analyzer based on the determined parameter of the quality control.

Description

technical field [0001] The present invention relates to methods for monitoring the performance of analyzers for biological samples and automatic analyzers for biological samples. Background technique [0002] Automatic or semi-automatic analyzers for biological samples are used in a variety of clinical or laboratory settings. Typically, the results of measurements performed by such automatic or semi-automatic analyzers may form the basis of a medical decision, such as a medical practitioner's diagnosis and / or treatment decision. Therefore, automated or semi-automated analyzers usually must undergo rigorous quality control procedures. [0003] An example of such an analyzer is a device for performing in vitro diagnostic (IVD) methods, which are widely used, for example, to help diagnose disease or monitor the effect of treatment. In IVD devices (as well as in other automated or semi-automated analyzers for biological samples), quality controls are inserted periodically or i...
