Figuring out what kind of snake bit you makes for a good plot in tv shows, but at least for North America, there are only two types of venom (vipers and corals) and coral bites are very rare, and can be treated without the anti-venom (it's a paralytic, so the person can be intubated until it wears off and can breathe on their own again). Last I checked, the coral anti venom isn't even available in America anymore, as it was only getting used something like 3 times a year, out of thousands of doses manufactured. So basically, generic viper anti-venom is all that is available locally. I don't know the answer to your question, but practically, it's basically irrelevant bc if it doesn't respond to the available viper av, the treatment is just supportive care.
