Perform a chemistry panel to evaluate for possible electrolyte disturbances; to look for laboratory evidence of dehydration (elevated blood urea nitrogen [BUN]/creatinine ratio), which tends to occur as the disease progresses; and to evaluate for glucose intolerance, which may be due to preexisting diabetes or sepsis-induced metabolic disturbance.

Arterial blood gas (ABG) sampling provides a more accurate assessment of acid/base disturbance. Acidosis with hyperglycemia or hypoglycemia may be present.
