A long-term evaluation of the CentrifiChem centrifugal microanalyser during routine use in the clinical biochemistry laboratory.
The CentrifiChem centrifugal microanalyser (model 300) has been used routinely in this laboratory for two years. Its reliability for performing total bilirubin, aspartate aminotransferase alkaline phosphatase and gamma-glutamyl transferase analyses during this time is reported, using methods modified in a preliminary study. Accuracy of the analyses has been assessed by comparing the results with those from other analytical systems and by using commercial control sera. Determinations have been made for within-batch, between-day (20 days), and long term (100 weeks) precision. Other aspects evaluated were the range over which methods were linear and the cost of operation.
