Automatic biochemistry analyzer in three cases must be calibrated

Automatic biochemistry analyzer in meet the following condition must always calibration:
First, change reagent manufacturer or batch number
Second and instrument, a big maintenance or replacement important components
Third, indoor qc reflects the trend of abnormal or bias beyond the provisions of the laboratory and can't figure it out for the accept limit.
In automatic calibration of biochemical analyzer, in order to ensure the accuracy of the determination results and other domestic and international laboratory comparable, for this is as follows:
Require and automatic biochemistry analyzer reagent and calibration product of form a complete set a detection system. Because of the reagent and instrument and supporting calibration products are imported, the price is expensive, basic-level hospital imported equipment, more than domestic reagents "noncognate" analysis model, which caused different source analysis system, serum "matrix effect" phenomenon outstanding, the impact of the instrument measuring results of the comparability and accuracy.
We derive Hitachi automatic biochemistry analyzer and Toshiba automatic biochemistry analyzer for the detection of failure experience, mixed with fresh serum as dissemination carrier, for calibration product to dissemination, determine the instrument calibration product in the determination of the actual system reagent at school, to to the instrument calibration, make the test results with traceability, in recent years to provinces and cities biochemical qc result is outstanding.
Automatic biochemistry analyzer in long-term use process, filter and the precision of the system with samples, photoelectric element may change the sensitivity and the light bulb is aging and other factors, lead to the deviation of the results was, so best once every six months calibration.
