Key investigations

Key investigations for MAOI poisoning are:

  • full blood count
  • serum electrolyte, urea and creatinine concentrations
  • serum creatine kinase concentration
  • blood gas analysis
  • electrocardiogram (ECG)—ST and T wave changes can occur
  • coagulation profile
  • computed tomography (CT) of the brain if intracranial haemorrhage is suspected.
