Blood is collected from the donor by inserting a large needle into a vein in the arm. Usually, one of the larger veins near the inside of the elbow is used. A tourniquet is placed on the upper arm
whole blood is collected, the desired blood component is removed, and the remainder is returned to the donor.
While the FDA does allow blood collection centers to compensate for blood donation, there are currently no centers in the U.S. that pay the donor. Blood components collected from such donors must be labeled "Paid Donor" instead of "volunteer donor". As such, regional hospital transfusion services are reluctant to accept such products.
A blood donor is a person who donates blood for use in transfusion.

O negative is the universal donor because when O+ve blood group is transfused to -ve blood group recipient, antibodies are produced which causes hemolysis of Rh +ve labelled blood cells. When O-ve blood is transfused to Rh +ve recipient, no antibodies are produced as donor blood has no Rh factor present on blood cells, so no transfusion reaction occurs. Thus, O -ve is universal donor.
Type O negative.
