Hypothesis
The BM/Hitachi 911 analyser will demonstrate acceptable performance metrics for clinical laboratory use.
Conclusion
The BM/Hitachi 911 analyser met the acceptance criteria for analytical performance and is suitable for routine and emergency analyses.
Supporting Evidence
- The mean coefficient of variation for within-run imprecision was less than 1.16%.
- Regression analyses showed slopes between 0.94 and 1.05, indicating good correlation with the BM/Hitachi 717.
- No relevant drift or sample-related carry-over was observed during the assays.
Takeaway
The BM/Hitachi 911 is a machine that helps test blood samples quickly and accurately, making it easier for doctors to get results.
Methodology
The performance was evaluated over three months using 100 serum samples and compared with the BM/Hitachi 717 analyser.
Limitations
The study did not address long-term performance beyond three months.
Participant Demographics
Serum samples ranged from normal to pathological values.
