Answer (A): I have one of those. The instruction booklet was in a slide-out pocket in the front of the box -- you may want to look again. I'll see if I can find it when I get home tonight.
Answer (B): The quality of your results from that test are likely about the same however you do it, or even if you don't bother doing it at all. Really not an effective test kit, in my opinion.
Cheers!
