Hypothesis
The Eppendorf ERIS analyser is suitable as a partial replacement for existing fast analysers at Ninewells Hospital.
Conclusion
The Eppendorf ERIS proved to be a reliable instrument with acceptable performance characteristics for the analytes studied.
Supporting Evidence
- The Eppendorf ERIS can perform up to 20 tests on each sample.
- It produces one result every 9 seconds after a 10-minute lag.
- Calibration is recommended weekly or when changes occur.
- Carry-over for most tests was negligible.
- Imprecision was acceptable for clinical purposes.
Takeaway
The Eppendorf ERIS can run many tests quickly and accurately, making it great for hospitals.
Methodology
The performance characteristics of various assays were evaluated using the Eppendorf ERIS and compared to a parallel fast analyser.
Potential Biases
The Eppendorf ERIS showed some positive proportional bias in iron and GGT results.
Limitations
Extensive studies on linearity, interfering substances, and recovery were not carried out due to time constraints.
Participant Demographics
Patients' sera were selected to cover the analytical range and represent typical specimens.
