Recently, various types of data processing systems for analytical clinical chemistry, especially for multichannel automatic analyzers, have been developed. However, relatively few of these systems include the function of process control and data correction.
We have devised a computer-controlled and data processing system connected with the SMA12/60 Auto Analyzer. The features of this system are described as having the adoption of: (1) a sample identification conception utilizing a commercial ID reader,(2) a real time correction of on-line data, based on our previous experience on the analyzer, for drift and sensitivity, carryover between specimens, and bilirubin interference for cholesterol value determinded by the Liebermann-Burchard reaction,(3) a feedback control and morlitor system of the multi-channel analyzer when the differences between the values of standards and monitoring samples are outside of the preset tolerance limits.
Here, we are reporting the principal instrumentation and software of this system and over3year experience on the system in our clinical chemistry laboratory.
