Locate
Use Yellow Pages or Google to locate your local blood plasma collection center, blood bank, or blood collection facility. If there are multiple centers near you, call to find out which one will pay the most.
Eat
It is a good idea to eat something and drink a lot of water before you donate plasma; it will keep you from getting light headed.
Screening
When you get to the facility, they will question you about your health history and behaviors that could put you at risk for being HIV positive.They will also ask you about recent tattoos and piercings, and you will undergo a physical examination, drug screening, and waiver signing.
Donate
After passing the screening you will then lie down and let the technician extract your blood plasma.
Get paid
You will earn around $30 per donation, and can donate up to twice a week. The first visit will take a couple hours because of the screening process, but after that visits will take around 30 minutes if the office is not busy.
