About

The purpose is to characterize the precision and in use stability of 19 parameters (pH, pCO2, pO2, cNa+, cCa2+, cCl-, cK+, cGlu, cLac, cUrea/BUN, cCrea, ctHb, sO2, FMetHb, FCOHb, FO2Hb, FHHb, FHbF & ctBil) in arterial blood drawn and stored in self-filling syringes (PICO70 and safePICO) across different lots of samplers measured on ABL90 FLEX PLUS analyzer.

The study aims to determine the total (within Lot and Lot-to-Lot) precision for the PICO70/safePICO in arterial whole blood. Furthermore, the study aims to determine the stability for up to 45 min. at room temperature (18-25 °C) for arterial blood sample analysis in the PICO70/safePICO for all 19 parameters.

Full description

The study is a Post-Market Clinical Follow-up (PMCF) randomized unblinded study, expected to be conducted at two sites in Denmark using arterial whole blood samples collected from adult patients to determine the precision and stability for the PICO70/safePICO syringes when measuring 19 parameters (pH, pCO2, pO2, cNa+, cCa2+, cCl-, cK+, cGlu, cLac, cUrea/BUN, cCrea, ctHb, sO2, FMetHb, FCOHb, FO2Hb, FHHb, FHbF & ctBil) using the RMED ABL90 FLEX PLUS analyzer. The 19 parameters will be analysed for each syringe in the syringe series on the ABL90 FLEX PLUS analyzer. For PICO70: Approximately 40+4 (4 contrived sample series) completed series of arterial blood samples consisting of 6 syringes: The syringes will be from three different lots (A,B,C) and analyzed at four different time points, T0, T15, T30 and T45. For safePICO: Approximately 40+4 (4 contrived sample series) completed series of arterial blood samples consisting of 6 syringes: The syringes will be from three different lots (A,B,C) and analyzed at four different time points, T0, T15, T30 and T45. According to guidelines (CLSI GP34) samples should be distributed throughout the analytical measurement range of measurands evaluated. To ensure coverage of the full range for each parameter, it may be necessary to contrive some sample series.
