Author information

Klinik für Nutztiere und Pferde der Universität Bern.


The purpose of this study was to compare the results of horse blood examinations on a portable blood analysis system, i-STAT SDI, with conventional laboratory equipment and to verify the accuracy and precision. The precision within run was high and the coefficients of variation ranged from 0 to 3.85%. The comparative analysis of patient samples with routine methods showed a very strong positive correlation with correlation coefficients above 0.96 for blood gases, pH, glucose, urea, hemoglobin, hematocrit, sodium and potassium, with the exception of chloride where it was 0.867. The i-STAT system provides a quick and accurate stable-side evaluation of laboratory data in critically ill horses and emergency situations.
