13 factors affecting biochemical analyzer test results

With a fully automatic biochemical analyzer, the entire process from sample addition to result is done automatically by the instrument. The operator only needs to put the sample on the specific position of the analyzer and select the program to start the instrument to take the test report. Since there are no manual steps in the analysis, there is little subjective error, and because fully automatic biochemical analyzers generally have automatic reporting of abnormalities and automatic correction of their own work status, the system error is also small, bringing great convenience to the user.

• 1. the quality of the reagents. Including stability, repeatability, accuracy, linearity, sensitivity, specificity and resistance to interference.
• 2. cross-contamination between reagents.
• 3. the effect of the sample on the assay result.
• 4. Incorrect collection methods.
• 5. sample hemolysis, jaundice, celiac disease and drug effects.
• 6. operator effects on results.
• 7. incorrect reagents and sample preservation methods.
• 8. incorrect assay parameters and calibrations.
• 9. other. Such as misplaced reagents and samples.
• 10. Influence of instrument parts on the determination results.
• 11. optical colorimetric accuracy, stability and linear range.
• 12. temperature control accuracy, volatility and temperature rise time.
• 13. spiking accuracy and repeatability.
