Berlin · New York Investigation of the Performance of the ES 600 Enzymun-Test ® System A Multicentre

Summary: The ES 600 sample^selective multibatch analyser was subjected to a multicentre evaluation in six laboratories in accordance with ECCLS guide-lines. During the 3-month trial, five Enzymun-Test ® diagnostics (T4, TBG, Digoxin, CEA and TSH)') were measured at 25 °C. The study yielded the following results: 1. The within-series and between-series precision were very good, with mean CV's of approx. 3 % and 7% respectively. 2. Recovery of the target values for three control sera was in the range ±5%. 3. A trend in measurements did not occur in any of the methods investigated (for series of over 240 determinations). J) T4 = tfcyroxine, TBG = thyroxine binding globulin, CEA = carcinoembryonic antigen, TSH = thyrotropin
