Autologous
self
Chagas

Confidential unit exclusion
a method whereby a donor may confidentially ask that his/her blood not be used for transfusion, this may be accomplished by the use of a barcode system in which the donor privately selects an appropriate barcode stating to use or one stating not to use the donation
Deferral
prevention of donation, either temporarily or permanently, because of failure to meet donor acceptance criteria
Directed donor
donor chosen by the potential recipient, such donations have been proven not to be any safer than transfusions from the general population
Donor processing
testing and preparation of donor blood before it is considered available for distribution, including ABO, Rh, antibody screen, & infectious disease testing
Good manufacturing practices
GMPs, 200 & 600 series of the Code of Federal Regulations that regulate blood banking practices
Hematocrit
measure of the volume of RBCs as a percentage of the total volume of whole blood
Hemoglobin
iron-containing pigment in RBCs that functions to carry O2 from the lungs to the tissues
High-risk donor

Infectious disease markers
substances in the serum/plasma that indicate exposure to or presence of a particular disease
Intraoperative blood salvage
procedure in which blood is salvaged, usually through a suction device, & re-infused with or without filtration to a patient during a surgical procedure
ISBT 128
International Society for Blood Transfusion
Mobile operation
collection operation which is not a fixed site
Nucleic acid testing
sensitive laboratory testing which tests for DNA/RNA
Paid donor
donor who receives payment for his/her donation
Post operative salvage
procedure in which blood is salvaged from a draining wound for re-infusion, useful in some forms of cardiac surgery
SOP
statement of the exact process used to establish a task
Surrogate markers
disease markers that are indicators of potential for infection with other, often more serious, infectious diseases
Syncope
fainting, vasovagal response
Traceability
ability to trace back to a source
Uniform donor history questionnaire
list of donor interview questions developed by the AABB & recommended for use in screening blood donors
Volunteer blood donors
person who donates blood/blood components with no compensation readily convertible into cash
Window period
period of time in serologic testing when the markers usually indicating disease are not detectable, although disease is present
