Conclusion
The Cobas Bio analyser demonstrated acceptable imprecision and accuracy for various biochemical assays.
Supporting Evidence
- The imprecision for all methods investigated was acceptable.
- The accuracy of the pipetting system was confirmed by comparing absorbances with those obtained on standardized spectrometers.
- The Cobas Bio complied with all clauses of the ASC100 investigated, apart from a few limitations.
- The test method showed satisfactory agreement with routine methods of analysis.
Takeaway
The Cobas Bio is a machine that helps test blood samples quickly and accurately, making it easier for doctors to get results.
Methodology
The study evaluated the performance of the Cobas Bio analyser by comparing its results with those from standard methods across various biochemical tests.
Limitations
The analyser can only hold 25 specimens at a time, requiring operator presence to change sample discs, and it takes longer to equilibrate to the selected temperature than indicated.
Participant Demographics
Eighty patient samples were assayed.
