RESUMO
We evaluated a new multi-channel chemistry analyzer, the Hitachi 705 Automatic Analyzer, marketed by Boehringer Mannheim Diagnostics, Inc. The instrument is a computer-controlled discrete analyzer, which can be run in a combination profile mode and single-test mode. Sixteen different tests per sample may be performed at the rate of 180 tests per hour. The Hitachi 705 is especially suitable for use in hospitals that do not perform profile testing. Precision and linearity were excellent and the instrument was relatively trouble-free, with little operator attention required during operation. The Hitachi 705 was easily interfaced to our laboratory computer. We compared the performance of the instrument with that of the Du Pont aca; the two instruments compared favorably.
