Conclusion
The evaluation of the Technicon Axon analyser was satisfactory for routine use in a medium-sized laboratory.
Supporting Evidence
- Photometric inaccuracy was acceptable at both 340 nm and 404 nm.
- Imprecision was greater at lower absorbances.
- Drift was negligible over a 12-hour period.
- Within-run imprecision was acceptable for all analytes tested.
Takeaway
The Technicon Axon analyser works well for testing samples in a lab, showing good accuracy and precision.
Methodology
The analyser was evaluated based on guidelines from the Sociedad Española de Química Clínica and the European Committee for Clinical Laboratory Standards, focusing on various performance metrics.
Limitations
Some between-run imprecision values were unexpectedly high, which may relate to reagent quality rather than the instrument itself.
