Clinical Assessment: Laboratory Tests

Some laboratory tests relevant to envenomation

Immunological

• Snake Venom Detection Kit

Clotting studies

• INR/PT
• APTT
• ACT
• D-dimer
• X-FDP
• fibrinogen
• In remote areas where sophisticated clotting tests may be unavailable, a 20-minute whole blood clotting test can be performed.
  
  

Enzyme assay

• creatine kinase

Urinalysis

• haemoglobin
• myoglobin

   Note: renal function may be impaired secondary to myoglobinuria or other mechanisms.

FBE

• WCC is usually only mildly elevated. A significantly raised WCC may indicate other pathology.
