So, independent means truly independent, so if I'm working with even one other person/group of people, it is no longer independent?
I'm currently working in a lab doing a part of a clinical trial as well, and I HAVE to rely on MDs to take the sample since it targets a sensitive area, but I do everything else including obtaining consent forms, explaining the project to the patients, and other stuff except for the actual collection in terms of data collection and management.
This one I can describe in depth much more readily and comfortably, because my other one didn't do so hot 🙁 I could, if I had to, present a fairly long speech about the project to an MD in the field to the point that they would understand the process, from sample collection to how the clinical trial object ACTUALLY WORKS.
