Agreement of Electrolyte Measurements Between Arterial Blood Gas Analyzers and Central Laboratories in Critically Ill Patients with Acute Kidney Injury
Among 1,870 critically ill patients with acute kidney injury, sodium and potassium from arterial blood-gas analysers showed relatively good agreement with central laboratory values, with potassium having the narrowest limits. Clinically meaningful discrepancies occurred in 7.0% of sodium, 14.1% of potassium and 31.4% of chloride measurements, so rapid bedside results should support rather than replace reference testing.
