What did you do in class today, Honey?

Well, I peed in a cup. I had to do urinalysis on my own urine. They make fake blood for blood typing in lab, why can't they make fake pee? I feel like its some invasion of privacy, making me a Guinea pig for our exercises in lab.  Isn't this some HIPAA violation? I was in the control group that didn't have to eat chips and drink water.
As far as being my own guinea pig, I wonder if it's like that in nursing classes, too?
