I thought they said IV bags interfere with the tests for EPO or something like that. Some fighters just going to have to move up I guess. 
Molsonmuscle360 -stonepony -Molsonmuscle360 -GrilliamG - From what I've read, it has something to do with the saline from the IV bag being something commissions can test for
It's the plastics. Trace amounts leak into the IV and into your system
Saline is simple to make. I can't imagine traces of plastic would be much of a roadblock.
Yeah, they would. Unless you are an idiot, you aren't going to take an IV from a non sterile vessel. IV bags use a very specific form of plastic that is easy to find in blood tests. Say someone started using a glass bottle for instance. They are running two serious risks. Contamination of the bottle, and air bubbles in the IV solution. Both of which could be potentially fatal.
Who suggested a non sterile vessel?
Neither sterilization nor a non-plastic vessel are any kind of a roadblock.
The only thing it will do is is increase the chances of someone getting hurt do to improper rehydration. 
Fuck shit up
It's definitely to help prevent guys doing blood/EPO doping.
