Conclusion
The Monarch chemistry analyser demonstrated good performance over a wide range of analytes, although the performance of the TCO2 and calcium methods were disappointing.
Supporting Evidence
- The within-batch and between-day precision data were good in the majority of cases.
- Method comparison studies showed good agreement, with small discrepancies due to different calibration material.
- Major discrepancies were found with CK and LD assays.
Takeaway
The Monarch chemistry analyser is a machine that tests blood samples quickly and accurately, but it sometimes struggles with certain tests.
Methodology
The performance of the Monarch was assessed for 19 different analytes, focusing on precision, accuracy, calibration stability, and carry-over.
Limitations
The performance of the TCO2 and calcium methods were disappointing, and discrepancies were found in enzyme results.
