[Use of the Reflotron system for the determination of creatine kinase (CK) in the blood of swine, sheep, cattle, horses and dogs].

The Reflotron-CK test was evaluated with blood samples of healthy and diseased pigs, sheep, cattle, horses and dogs in relation to the standard CK-NAC test (UV-method). The precision within the series on the day of blood sampling was better than VK = 7.5% (coefficient of variation) with both methods. The day to day precision was estimated by using deep frozen plasma and was in the same order of magnitude with the Reflotron-CK and the UV-method (CV less than 10%). While fresh whole blood of sheep, cattle, horses and dogs respectively should be applied directly onto the dry reagent carrier with the Reflotron-pipette (32 microliters), the blood samples of pigs must be diluted (200 microliters 0.9% NaCl-solution and 32 microliters blood, factor 7.25) before determination with Reflotron-CK. In the five species mentioned the correlation between Reflotron-CK and CK values obtained with the standard UV-method was satisfactory (r greater than 0.96). Systemic deviations of the Reflotron-CK values should be corrected by calculation formulae, given in the paper.
