Hypothesis
The analytical performance and practicability of the Boehringer Mannheim/Hitachi 911 analysis system will meet established acceptance criteria across multiple laboratories.
Conclusion
The study confirmed that the Boehringer Mannheim/Hitachi 911 analysis system is a useful and versatile tool for clinical laboratories, meeting most performance criteria.
Supporting Evidence
- The study included over 100,000 data items collected over three months.
- Nearly all analytes met the imprecision limits set at the beginning of the study.
- The system showed no relevant drift effects over an eight-hour period.
- The acceptance criteria for analytical performance were fulfilled in most laboratory segments.
Takeaway
This study tested a new lab machine to see if it works well for different tests, and it mostly did a good job.
Methodology
The study involved a multicentre evaluation across six European laboratories, testing various analytes according to ECCLS guidelines.
Potential Biases
Potential biases due to differences in calibration and method application across laboratories.
Limitations
Some analytes did not meet acceptance criteria, particularly for sodium and chloride assays.
Participant Demographics
Involved six laboratories from different European countries.
