If you want to have your B.O.A.L. tested you could cape it out before they cut out the lymph nodes. You could also cut the lymph nodes and sent them in for testing yourself. It's pretty simple and there are many videos on how to do it: https://www.youtube.com/results?search_query=cwd+testingWe have CWD in our local counties here in Illinois. We're required to check our firearm season deer in person and they ask if they can sample. Generally everything gets sampled except for bucks that will be shoulder mounted since they cut the neck. For archery season they have drop boxes where you can throw heads to have them checked.
I've never had a positive gun deer and I haven't had any archery ones checked yet. If I ended up with a positive result I wouldn't eat it nor would I feed it to my family.
