The objective was to evaluate the automatic ELISA Triturus analyser in order to assess its practicability and imprecision. The analyser was evaluated according to the guidelines of the Spanish Society of Clinical Chemistry. The evaluation was performed in two steps: evaluation of the imprecision and the inaccuracy of a semiquantitative and qualitative technique, and study of the practicability. The within-run imprecision rate ranged from 8.9 (VC) to 10.2% (VC) for the semiquantitative test, and from 11 (VC) to 17.2% (VC) for the qualitative one. The between-run imprecision rate ranged from 6 (VC) to 9.7% (VC) for the semiquantitative test, and from 8.8 (VC) to 18% (VC) for the qualitative technique. No sample-related carryover was detected in negative samples. The relative inaccuracy was correct for both techniques. Non-specific binding caused by waste products from the analysed circuits was not detected. The Triturus analyser is a reliable open analytical system with a considerable working capability, rendering this apparatus adequate for conventional laboratories with a medium-to-high work charge.
