Hypothesis
The use of cusums can provide more information about assay quality than simple graphical plots.
Conclusion
The proposed cusum method allows for instant quality control assessment in clinical chemistry laboratories.
Supporting Evidence
- The cusum method provides a more sensitive measure of assay quality than traditional methods.
- The system allows for instant feedback on assay performance.
- Using a microcomputer simplifies the calculations needed for cusum analysis.
Takeaway
This study shows a way to quickly check if lab tests are working well by using special calculations called cusums.
Methodology
The study describes a method for using cusums in quality control of clinical chemistry assays with specific instruments and software.
Limitations
The method requires a dedicated microcomputer during analysis, which may not be feasible for all laboratories.
