Jj. Chance et al., Multiple site analytical evaluation of a portable blood gas/electrolyte analyzer for point of care testing, CRIT CARE M, 28(6), 2000, pp. 2081-2085
Objective: To evaluate the analytical performance of the SenDx 100 portable
blood gas and electrolyte analyzer (SenDx Medical, Carlsbad, CA).
Design: Accuracy was evaluated by correlation of whole blood patient sample
s with the Nova Stat Profile 5 (Nova Biomedical, Waltham, MA) and the Ciba
Coming 865 (Chiron Diagnostics, Medford, MA). Precision was evaluated using
quality control materials (RNA Medical, Acton, MA).
Setting: Critical care laboratories and operating rooms in two institutions
.
Measurements and Main Results:Precision studies performed at three differen
t concentration levels for each analyte demonstrated intra-assay precision
of less than or equal to 2.5% coefficient of variation and interassay preci
sion of less than or equal to 4.0% coefficient of variation in all cases. A
nalysis of patient specimens in general showed good to excellent correlatio
n to reference analyzers. Regression Variables are tabulated.
Conclusions: The SenDx 100 portable blood gas and electrolyte analyzer is a
simple and easy to use analyzer demonstrating acceptable performance compa
red with reference methods.
