Screening canceled many times

okay so I've been doing studies since 2012 and i never had a problem with PPD screening or anything. But recently since August of 2014 I've signed up for a screening (i made sure i was among the first 5 callers) and 2 days before screening i get a call from them saying that "the study is been filled." i was in a little shock. well this happen 2 more times in a row! what is going on? some one told me that its because they are trying to get new people from the schools and trying to filter out the veterans. have you guys heard anything?

Who knows what their deal is, I never had luck there after screening 4 or 5 times when I was in that area like 3-4 years ago.
I found them to be extremely picky and fussy with regards to lab results- even when I almost never had problems with this at any other clinic.
I don't know if they might have a preference for younger college age people, maybe this makes sense as they will tend to have less issues, but the vast majority of people at their screenings are older than that.
