Repeatability of results from three in-house biochemistry analyzers and a commercial laboratory analyzer used in small animal practice

摘要: The repeatability (precision) of clinical pathology results is vital for confidence in the measured values. Comparison to biological variation an accepted standard instrument/method performance human pathology. This study aims assess precision biochemistry from three in-house analyzers and one commercial laboratory analyzer relation compare between analyzer. Two commercially available quality control materials (QCMs) were repeatedly tested on same different days. Coefficients calculated assessed published data cats dogs. In-house compared laboratory. Seven 13 analytes met desirable standards QCM minimum other all both For more than half determinations across analyzers, was as good or better most generally high, so large differences repeated patient are probably due changes rather variation.
