Blood donors are often recruited for transfusion purposes.  There are specific guidelines that blood banks must follow when collecting blood from donors.  These guidelines are put into place to ensure quality and standardization.  All blood banks are regulated by the United States Food and Drug Administration because blood products are classified as being pharmaceutical.

Blood donors must be at least 17 years old.  Most donors are not older than 66 years old unless the blood bank physician approves.  Donors must meet specific weight requirements.  They must be at least 110 lbs.  Minors who would like to donate blood must have written permission from their parents.   Every potential blood donor must undergo a brief physical examination and complete medical history.  This is important to determine the patient’s health.  This information is collected each time a person donates blood no matter of frequently.  Any information disclosed by the donor should be kept in strict confidence.  Every donor is required to provide written permission for the blood bank to use any blood that is collected.

There are certain collection principles that should be followed when collection blood from a donor.

-Donor blood should be collected from the large antecubital vein.
-The collection unit should be sterile, in a closed system that contains a bag connected to a length of tubing with a sterile 16 to 18 gauge needle.
-The bag should be placed lower than the patient’s arm.
-Each donor unit usually contains about 450 mL of blood when full.
-Only one needle puncture can be used to fill a unit.
-Partially filled units are not acceptable.   If a unit is partially filled the procedure must be repeated with an entirely new unit.
