Wow this section took me longer than nearly any other to produce, as I had a lot to learn. HUGE thanks to Jordan Benjamin at the Asclepius Foundation for taking the time to talk through the podcast and update me on antivenom personally. He is a GREAT resource, and AFTER YOU HAVE DONE THE MODULE if you have any questions he has expressed enthusiasm for helping you with any snake-bite-related topics.
Start with the podcast, and review the Asclepipus slide set with algorithms. Have the POLYSERP insert available to you. Have the WHO database available to you. This should arm you with everything you need to figure out the test, although if you need more detail on a specific snake species Toxinology is also there for you.
