Assessment

Laboratory assessment of caffeine blood levels cannot be easily obtained, but are not necessary for the management of clinical symptoms. A urine drug screen and thyroid studies are beneficial when exploring the differentials of substances of abuse or hyperthyroidism. An electrolyte panel is necessary for the careful assessment and correction of hypokalemia and hypomagnesemia. This is particularly important in the presence of ventricular dysrhythmia.
