Blood from someone else that matches yours, usually from a volunteer blood
donor. Also referred to as homologous blood.
The process of making an antibody against a foreign antigen.
A pathological deficiency in the oxygen-carrying component of the blood,
measured in unit volume concentrations of hemoglobin, red blood cell volume,
or red blood cell number.
Proteins that react with antigens on red blood cells and may destroy transfused
red blood cells.
A substance that prevents the clotting or thickening of blood.
A substance on the surface of red blood cells that elicits an immune response
when transfused into a patient who lacks that antigen.
A procedure where whole blood is removed from the body and a desired component
is retained, while the remainder of the blood is returned to the donor. Apheresis
procedures normally take 45-90 minutes.
An anemia caused by deficient red blood cell production by the bone marrow.
The process of making antibodies against one’s self (one’s intrinsic
antigens).
Blood drawn from an individual prior to surgery and given back to the same
individual when and if a need for transfusion arises.
A special kind of apheresis donation, Automated Blood Component (ABC) Collection
allows donors to give only those blood components need for patient transfusions.
The needed blood components are separated while the donor is in the chair.
ABC collection can yield all three components (red cells, platelets, and
plasma) or a combination (such as red cells and platelets) from just one
donor.
Automated Red Cell Collection (2RBC) allows the donor to give two units of
red blood cells, instead of just one. The process separates your blood into
its components while it is being drawn. Because only red blood cells are
being collected, there will enough for two red cell transfusions. The remaining
components are returned to the donor.
Enthusiastic representatives of an organization that publicize the blood
drive and recruit donors.
Everyone’s blood falls into one of four groups, or types: A, B, AB
or O. The type depends on the presence or absence of certain substances on
red blood cells. Blood types are inherited.
The soft tissue located in the cavities of bones which is responsible for
blood cell and platelet production.
A soft, fat-like substance found naturally in the body.
A virus that may cause flu-like symptoms in the general population, but may
cause severe disease in premature babies, bone marrow transplant recipients,
and AIDS patients.
A "part" of blood. Blood is made up of different "parts" or
components: red blood cells, plasma, platelets and several types of white
blood cells. Each component has its own job to do. We can separate blood
into components so patients can be transfused only with what they need.
To find similarities between a patient’s blood and a donor’s
blood using laboratory tests.
A donation made by a blood donor who wishes his or her unit of blood to go
to a specific patient.
To give blood. A blood donation is about one pint. Specific components, such
as plasma or platelets can also be donated.
The process by which transplanted or transfused cells (for example, after
a bone marrow transplant) begin to grow and reproduce themselves within the
recipient.
Pertaining to people with origins from different parts of the world.
A clotting factor that stabilizes blood clots.
Contains the clotting factor used to control bleeding in hemophiliacs.
A protein involved in coagulation. Fibrinogen reacts with other molecules
to produce blood clots.
A reaction where transplanted or transfused cells attack the recipient’s
own cells.
A type of white blood cell that attacks and destroys foreign substances.
A measure of the amount of red blood cells in your body.
Of the blood.
A blood specialist.
The molecule in the red blood cell that carries oxygen. Hemoglobin combines
with oxygen in the lungs and releases it in the tissues. It is what makes
blood red.
The process of clotting.
Inflammation of the liver, caused by infectious or toxic agents and characterized
by jaundice, fever, liver enlargement, and abdominal pain.
Antigens present on most cells of the body which are unique to the individual.
It may be considered to be the individual’s genetic fingerprint.
A virus that may cause blood or nerve disease.
An autoimmune disease where the body makes antibodies against its own platelets.
A condition brought about by disease or chemotherapy where the individual
is highly susceptible to infection.
Red blood cells treated with radiation to inactivate white blood cells which
may cause graft-versus-host disease.
Another term for a white blood cell.
Prevent transfusions reactions caused by white cells contaminating red cell
and platelet preparations and may reduce the likelihood of certain infections.
Removal of white blood cells from products in order to prevent certain transfusion
reactions such as fever, chills, and alloimmunization.
A leukocyte that directs the formation of antibodies, and that has memory.
Pertaining to all chemical functions within the body.
Another term for cancer.
Refers to the brain, spinal cord, and nerves.
Refers to transfusion reactions where the red blood cell is not destroyed.
A term for the study of cancer.
A term for disease.
The recovery, washing and reinfusion of a patient’s own blood, which
has been lost, during and after surgery in order to reduce the need for transfusions.
The removal, separation and freezing of peripheral blood or marrow, which
contain stem cells, for later reinfusion to restore a patient’s blood
manufacturing capability after radiation or chemotherapy.
Plasma is 92% water, 7% protein and 1% minerals. Plasma is the source of
gamma globulin, albumin and clotting factors. Plasma is used to treat clotting
disorders, burn victims and shock. When frozen, plasma lasts one year.
An apheresis procedure where platelets are collected.
Colorless cells whose main function is to control bleeding. Platelets are
essential to normal blood clotting. They can be wiped out during treatment
for cancer, leukemia, aplastic anemia and other diseases. They have a very
short life span; only 5 days.
Red cells transport oxygen to body cells and remove carbon dioxide. Red cells
contain iron in the hemoglobin. Red cells can be kept for 35-42 days.
Used to identify and cross-match rare blood groups and components for hospitals,
and then supply those units.
The Rh factor is an inherited blood group on red blood cells like the ABO
blood types. About 85% of the people in this country have it. Those who have
it are "Rh-positive," those who don’t are "Rh-negative."
Salt water.
A disease in which the affected person makes an abnormal hemoglobin. Sickle
cell disease is inherited.
Process which separates certain blood components from a patient so that hospitals
can either replace or treat them before reinfusion.
Replacing blood or blood components a body has lost in surgery, through an
accident, or as a result of medical treatment such as chemotherapy.
A low platelet count.
A disease state in which red blood cells and platelets are destroyed and
the body produces excessive blood clots which may damage the kidneys and
nervous system.
A person who has blood type O negative and is therefore able to serve as
a donor to a person of any other blood group in the ABO system.
A person who has blood type AB positive and is therefore able to receive
blood from any other group in the ABO system.
Refers to the effect of thinning of the blood by a medication known as warfarin
or coumadin.
The protective cells in the bloodstream. They attack bacteria by squeezing
through capillary walls to reach the area of infection. |
