Why does drug testing cost so much?

I apologize if there is a thread on this already. But on the IPhone app, I can't search for old threads. Could somebody explain or put a link up explaining why it costs so much to drug test. Phone Post 3.0

I don't think even most officials understand what exactly makes the tests cost so much, according to Brian Stann anyway. He was on the MMA hour talking about how he wanted to help represent Zuffa on the issue, and try to find out exactly what makes the drug tests cost so much.
