  • Title: [Evaluation of portable point of care instrument: the i-Stat . Report of 7,000 analyses].
    Author: Feuillu A, Morel I, Mollard JF.
    Journal: Ann Biol Clin (Paris); 2002; 60(2):153-64. PubMed ID: 11937440.
    Abstract:
    To validate the use of the i-STAT portable point-of-care instrument, performance checks have been conducted to verify its accuracy for PCO2/PO2 (tonometry) and precision for pH/PCO2/PO2 (control solutions). Results obtained with the i-STAT (pH/PCO2/PO2/Hct) were also compared to those provided by the Bayer Rapidlab 865 routinely used in our laboratory. All these measurements have been conducted under the same conditions using three types of i-STAT cartridges (G3, EG6, EG7) with two of different life duration to each cartridge with a view to observing their potential variability between types and any effect that ageing may have on analytical performances. Differences observed in this respect are not clear enough to draw firm conclusions. On the other hand, we consider the level of PCO2 and particularly PO2 performances not sufficient to warranty their use in the absence of a very strict quality control coupled with a highly developed clinical sense. No real use can be made of values noted for hematocrit (1998 survey).
