Snake venom detection


Swab from the bite site, even if it has been washed. If the patient has systemic symptoms and the bite site is of poor quality, urine is a useful alternative. A blood sample should only be used if neither of these specimens is available. A swab from the fangs of the dead snake may be used if available.




Identification of the venom involved in a clinically significant envenomation by an elapid snake in Australia or Papua New Guinea.


A positive result indicates the presence of venom and whether it originates from a snake of the tiger, brown, black, death adder or taipan families. The result guides the choice of antivenom to use if there is clinical evidence of significant envenomation. Occasional false positive results occur. Sea snake venoms are not reliably detected.
