Conclusion
The study emphasizes the need for quantifiable criteria to objectively select analytical instruments in clinical chemistry.
Supporting Evidence
- Clinical chemical analyses are required for diagnostic and prognostic purposes.
- Instrument manufacturers often claim universal applicability, but practical experience shows this is rarely the case.
- Criteria for instrument performance include analytical reliability, precision, accuracy, and detection limit.
Takeaway
Choosing the right tools for testing in hospitals is complicated, and we need clear rules to help make those choices better.
Methodology
The study reviews various criteria for selecting analytical instruments based on medical, methodological, and organizational aspects.
Potential Biases
The lack of objective rules may lead to biased evaluations based on subjective experiences.
Limitations
There is currently no consensus on universally acceptable testing protocols for all criteria.
