Laboratory Studies

See the list below:

  • Standard laboratory tests for poisoned patients are indicated if the patient has significant symptoms.
  • Quantitative levels of monoamine oxidase inhibitors are not clinically useful.
  • Electrolytes with lactic acid to evaluate for acidosis due to hypoperfusion
  • Toxicology screens are primarily useful in ruling out other toxins.  Acetaminophen level should be ordered in every patient with intentional overdose.
  • Obtain pregnancy tests in women of childbearing age.
  • Consider workup for hypertensive emergencies if any signs or symptoms are present.
