investigations to find out if the patient has been envenomated include testing with a snake venom detection kit which will alert if there is venom located around the bite site. however this doesnt necessarily mean that the person has been envenomated – it could just be that the venom is present on the outside of the skin that was tested so waiting for symptoms to arise such as ptosis = drooping of the eyes which is particularly common with snake bites in australia as well as muscle weakness mimicing paralytic signs will suggest envenomation, or doing a urine test – a urine test which tests positive for blood will indicate envenomation (provided the patient doesn’t normally have blood in their urine due to another cause) and this is because of muscle breakdown.  antivenom is then only used if the patient has been envenomated.
