Overview

Laboratory investigations may be helpful in establishing diagnosis and directing management of shock.

Laboratory Findings

  • Complete blood count
  • Electrolytes
  • Coagulation panel (PT, PTT, INR, etc.)
  • Cardiac markers
  • Liver function
  • Renal function
  • Lactate
  • Hyperlactatemia generally reflects the development of anaerobic metabolism in hypoperfused tissue and/or imparied hepatic clearance.
  • Lactate level could decrease within hours with effective therapy.[1]
  • Arterial blood gas
  • Cultures
  • Nasogastric aspirate
  • Pregnancy test
