Hypothesis
The analytical performance of the Dimension XL clinical chemical system was evaluated against earlier models.
Conclusion
The Dimension XL demonstrates analytical equivalence to previous Dimension systems and is capable of assaying 52 analytes with a throughput of 740 tests per hour.
Supporting Evidence
- The Dimension XL has a throughput of 740 tests/hour.
- Regression analysis showed slopes of 0.93 to 1.03 and correlation coefficients >0.96 for 28 assays.
- The system includes features like automated reagent loading and unloading.
- Precision performance was evaluated according to NCCLS protocol EP5-T2.
Takeaway
The Dimension XL is a new machine that can test many samples quickly and accurately, making it easier for hospitals to get results.
Methodology
The evaluation included precision studies and split sample correlation of tests compared to the Dimension AR.
Participant Demographics
Samples were obtained from hospital patients and normal subjects, including hemolysed, icteric, and lipaemic samples.
