Yep, I did this for a while too, back in the very-poor days of yore.
First and foremost, I presume the thought of needles and blood doesn’t disturb you, even if it’s your own? If it does, ya probably wanna think about other options. You’ll get poked a LOT.
They gave me a finger-prick (not a prick-fingering, which would have been much nicer considering the cute attendee I usually made it a point to visit… but I digress) EVERY time I went in. This, presumably, was to test for any number of conditions including diseases. Then of course once they hook you up, it’s with a big needle that stays in your arm for up to an hour.
Despite what they say, it WILL leave a scar, but only a small one. I was very insistant, and managed to ONLY get my left arm stuck. Kept my right elbow scar-free. Dunno why that was important.
Other than that, it’s a relatively pleasant experience. Comfy recliner-chairs to sit in, and they always had a movie going on the TVs. It wasn’t always a GOOD movie, but at least it was something. And I had a book anyway.
The place I went didn’t give any juice and cookies… except in the vending machines.
I think that I got $25 a pop, and that’s because I am large enough they could take the “Jumbo-sized” plasma bottle out of me without causing harm. I offered to try two of the little ones some day, but they didn’t like that idea much.
They set up a schedule for you based on weight health etc etc. Most people can donate (plasma only, whole blood donation is different) up to twice a week. And there were bonuses for donating more often.
Risks? Hmm… if you’re reasonably familiar with sterilization and it’s purpose, and keep a watchful eye on the people with the needles, you won’t have much to worry about. Don’t hesitate to ask questions, they expect it.
Basically they stick you with a needle. Then they attack a tube to it, which goes up into a machine. The machine contains a centrifuge, which separates the plasma from the rest of the blood (primarily red blood cells). A quantity is pumped out of you into the machine, run thru, then the red part is pumped back in thru the same needle. It takes several of these cycles to produce a full ‘batch’ of plasma.
The needle, the plastic tube, and the parts of the machine that the blood contacts, are all supposed to be installed new from packages opened and installed in front of you. No part of the system that touches blood is supposed to be re-used. Ask them to show you the machine the first time, you’ll see how it works, it’s pretty simple. You can actually watch the blood come out of you, get separated, and get pumped back in, with the plasma dripping into a plastic bottle.
One night before I donated I ate a very heavy ‘snack’ of cheese and sausage. There was a distinctly visible difference in the color/quality of my plasma. Eeewwww.
Oh, and there’s an IV bag, but it’s hooked to the same needle that pumps blood in and out of you. They say it contains anticoagulants and water to rehydrate you and prevent blood clots. It can be pretty cold when they pump you full of it, and wearing a sweater doesn’t help at all. Some people find this the most unpleasant part of the whole thing, but I kinda liked it.
As smeghead mentioned, plasma isn’t generally used by itself, but is processed into other products. These, in turn, bring in mighty large profits for the company producing them. So you’re providing a raw material, and they’re buying it off (out of) you.
I hate to think what my $25-worth of plasma went for when processed and sold… but it put food in my mouth, so good enough. :::shrug:::
