Cost is $100 per sample plus whatever your vet would charge to draw blood and ship it to the lab. The lab fee includes both the H&E and the IHC blood tests.

Based on the fee I don't see mass testing becoming the norm, unless someone is trying to clear a collection due to a suspected IBD diagnosis and/or death of one of the snakes in it.
