OBJECTIVE: The aims of this study were to define the maximum clinically acceptable difference between potassium concentrations on different samples and to determine the degree of agreement between potassium concentration measured on blood gas analysis and serum for patients with diabetic ketoacidosis (DKA). METHODS: This project comprised two sub studies. In the first, 15 emergency physicians, intensivists and endocrinologists were surveyed and asked to mark on a line with markings at 0.5 mmol/L intervals, the maximum clinically acceptable differences (both above and below the 'true' value) between potassium concentration measured on different samples. The maximum clinically acceptable diffe..View full abstract
