    • Culture & sensitivity test reveals the causative agents & the appropriate therapy especially when resistant organisms are suspected
  • Take blood cultures when patient appears ill & when infection is severe, recurrent, suspected to be an outbreak, or suspected to be caused by Methicillin-resistant S aureus (MRSA)
