Objective: Since there is a lack of current evidence to support the compatibility of the most commonly used arterial blood gas syringes with the latest multi-parameter analyzers, the objective of this study was to assess the agreement of analyte values between three heparinized arterial blood gas syringes using three different analyzers.
Methods: Venous blood from 25 healthy volunteers was drawn into the study syringes (BD Drihep A-Line, PICO50, and Portex Line Draw Plus) by four clinician volunteers in a random order (441 total) and immediately (<15 minutes) analyzed (ABL800 FLEX, RAPIDPoint 500, i-STAT System) in a randomized order. The Bland-Altman method was used to assess agreement of analyte values between the syringes for each analyzer.
