Note: Plasma is, basically, the water part of blood. When you donate plasma, you're given back your red blood cells so you don't feel tired/weak like when you donate blood. I get $35 a donation, and a person can go twice a week. I do this because I'm unemployed and enjoy eating. Bad experience #1: So I show up today at 6am. If you arrive even an hour later, there's a massive line of poor people. I decide to go with my right arm for a change. The tech (a guy named Eric) puts the blood pressure cuff on my arm and tells me to make a fist- all normal, it's how they get the vein to stand out so they can insert the needle. He's poking the crux of my elbow, trying to find a vein, and nothing's happening. He turns up the pressure to the point of agony until he finally finds it. #2 He very slowly and carefully inserts the needle. He then asks "So... Do your hands get cold much?" "Yeah, all the time" "Yeah... You have really bad circulation." Awesome! Eric gets the machine going, and I sit back and watch X-Men: First Class with the lovely African American gentleman next to me. After a few minutes, my machine starts beeping. Eric comes back, and tells me the machine thinks that there's no one attached. My pulse is THAT EFFING WEAK. #3 Eric asks me if I would like to be re-stuck in the other arm, but I, hating getting stuck, say no. I'm okay with being there longer if it means no more needles. He re-positions the needle and tapes it very carefully for the best blood flow. When he leaves, some other tech comes over and starts messing with the needle. From across the room, Eric yells "DO NOT TOUCH THAT". Too late. The other dude messed up the needle. Eric comes back and says, basically "Wow this is stupid. You'll still get paid, but I'm just going to start the cell return" #4 As the machine reverses to return my cells, I watch in horror as a dime-sized section of my skin, right beside the needle, starts to swell and ache. Eric sees, shuts off the machine, and tells me that the cells were depositing outside the vein. Yay bruise! #5 This means, in order to get my cells back, I must be re-stuck in my other arm. Awesome morning!
