Earlier in this thread, the infamous 2wipes1cup said no they don't, as of July 2013. Apparently nobody who posts has been there recently, hopefully you can update us! But yeah, as of then it didnt. How recently did you get out?
As of my last study there which was in July of 2017 they did not use VCT
I asked them (almost shooting myself in the foot) over the phone and they said they only use it for certain studies depending on the sponsor. I would find out if they use it on your studies before you have to travel there. April 30th 2019
