An evaluation of the Greiner Selective Analyzer and its role in the clinical laboratory

The Greiner Selective Analyzer (GSA II) was evaluated over a period of six months. The evaluation assessed the reliability, accuracy, and precision of the analyser for six determinations. The methods evaluated were for glucose, urea, creatinine, total protein, total bilirubin, and alkaline phosphatase. Comparison of results was also made with those obtained for the same specimens using the Technicon SMA 12160 Analyzer. Correlation and comparison of results indicate that the Greiner Selective Analyzer performed better for three of the methods but worse for serum creatinine determination. The role of the analyser as a routine tool in t heclinical laboratory was also evaluated during analyses of approximately 900 patient specimens. Other features evaluated were analytical range of the six methods under study, the economics of operation, temperature control, and electrical and mechanical safety. Additional key phrases: Accuracy, carryover, economics of operation, analytical ranges, reliability, precision.
