Conducting the ABL90 FLEX PLUS Clinical Precision Study for 15 Parameters in Adult Whole Blood is to validate performance claims for precision in heparinized whole blood for 15 parameters: pH, pCO2, pO2, cCa2+, cCl-, cK+, cNa+, cGlu, cLac, ctHb, sO2, FO2Hb, FMetHb, FCOHb, and FHHb, while being influenced by testing environment that is representative of intended use environment, site variability, and operator variability in a point-of-care (POC) setting.

The investigational device is the ABL90 FLEX PLUS incl. consumables, running SW3.5 MR2, manufactured by Radiometer Medical ApS The study is being conducted in Denmark and in total, a minimum of 30 subjects are to be enrolled to provide successful measurement values from 2 sites.

Adult Whole Blood is to validate performance claims for precision in heparinized whole blood for 15 parameters: pH, pCO2, pO2, cCa2+, cCl-, cK+, cNa+, cGlu, cLac, ctHb, sO2, FO2Hb, FMetHb, FCOHb, and FHHb, while being influenced by testing environment that is representative of intended use environment, site variability, and operator variability in a point-of-care (POC) setting.

Capillary blood collected into 2 capillary tubes from 2 distinct finger sticks will be measured on ABL90 FLEX PLUS in the Capillary mode (C65).

The study is designed to collect approximately 30 pairs of samples combined across sites.
