You are a donor if you give something to others. In blood donation, you can give blood if you are seventeen years old, weighs at least 110 pounds and be in your healthy shape before and during donation day. You are a qualified blood donor once you pass the examinations upon your arrival in blood bank. Apart from being qualified, a blood donor can also be one of the following:
1) Voluntary Donors
Voluntary donors give blood on a regular basis (every 56 days). You make it a habit to visit the blood bank either you’re invited or not. Upon arriving at the center, you are also given top priority because you’re consistently healthy. Your profile shows no major history of contagious diseases and you show more honesty in answering test questions.
2) Paid Donors
Somehow, the term “paid donors” is wrong. Donors aren’t paid with anything. If you get paid, that means you’re selling your plasma. Plasma is the yellow component of blood in which its collection process is called plasmapheresis.
Plasmapheresis takes more than an hour; that’s why, FDA-accredited plasma centers such as BioLife, Talecris, Octapharma Plasma Inc., CSL and Biomat USA decided to reward you after each procedure as their way of saying thank you. The amount of payment vary depending on the amount of plasma you sell, the frequency of visits and to what center you’re making a sell.
3) Potential Donors
You are labeled as a potential donor if you are recruited. Potential donors are expected to be qualified blood donors. You can pass the examinations but the only difference is – not all potential donors make it a habit to donate blood. You’re only a potential donor if you’re not a voluntary donor. Your presence is needed to prevent a major shortage in supply.
4) Universal Donors
You are labeled as universal blood donor if your blood type is O Rh- This blood type means there are no antigens in your blood and you can give blood to people with any blood type.
5) Deferred Donors
You are a deferred donor once you failed the examination. Either it’s a procedure for whole blood donation or plasmapheresis, you can be a deferred donor once you feel sick during the donation day, once you are pregnant, once you are infected with any sexual transmitted disease and once you have unprotected sexual contact with a prostitute or a stranger of the same gender.
