Whole blood electrolyte measurement: a comparative study

A comparative study conducted by the Biochemistry Laboratory of the University of Nantes has confirmed that the EXIAS® eI1 Analyzer delivers highly accurate measurements of sodium (Na⁺) and potassium (K⁺). The study compared results from whole blood and heparin plasma using EXIAS® eI1 with established automated systems, including the ABL800 Radiometer and cobas® pro/cobas® (Roche).

Study Highlights

• Whole blood: Sodium and potassium measurements on EXIAS® eI1 showed near-perfect correlation with ABL800 results, with no clinically significant differences.

• Heparin plasma: Measurements correlated closely with cobas® pro/cobas® pure, confirming reliable performance in plasma samples.

Implications
These findings demonstrate that the EXIAS® eI1 Analyzer provides precision and reliability comparable to best-in-class laboratory systems. Its performance ensures that clinicians can trust results for critical decisions, whether in the laboratory or point-of-care settings.

We are proud to share these results, reflecting our commitment to top-tier analytical performance.
