Thank you SouthLake. I think that's what I'm leaning towards.

We have ordered the test ourselves and are having a friend administer it. This is partially because my husband *might* think that I somehow helped him, but I also think that having someone else (a friend, who DS knows) do it is also likely to produce a more agreeable attitude. DS is the type of kid who generally enjoys performing for other people (when it's in an official capacity, like this).
