I am a college student and my friends are always looking for quick cash.. This is a method that I do not personally do, but some of my friends do religiously. If you want some quick money, you can sell your plasma. Plasma is not blood, its a yellow substance that transports nutrients to your cells. Plasma is very useful, in transfusions. Not only will you be making money, but you will be saving lives and helping scientist who research plasma. Here is how you do it: 1)Check your local papers or use google to search look up "for profit plasma centers". I promise plenty will pop up. 2) The first time you go expect to spend about two hours there. The doctors and nurses will put you through a general screening. They will ask you questions like "are you hiv positive" "do you have any piercings or tattoos" basically a lot of personal questions... but dont worry the screening is pretty lax and easy to pass.( unless your generally unhealthy) 3.)After your test the nurses will draw the plasma from your blood and test for iron levels, red blood cells etc. 4.)After your first visit your visits wont be any longer then 45 minutes and you will receive $30 dollars for your time =) you are allowed to go no more then two times a week.. Thats an easy easy $60 dollars a week and about $240 cash a month. Good luck. Have fun making easy money.
