Serum electrolyte levels are important to determine sodium concentration, which can guide resuscitation. Bicarbonate and potassium levels also are important to assess the degree of metabolic acidosis from volume depletion and tissue hypoperfusion as well a screen for coexisting hypokalemia. Blood urea nitrogen and creatinine levels measure renal function and intravascular volume. The glucose measurement may reveal hyperglycemia or hypoglycemia.
