A technique in which blood products are separated from a donor, the desired elements collected and the rest returned to the donor.

a procedure in which an animal's own blood is removed, particular fluid and cellular elements are extracted from the blood, then returned to the animal.

Procedure to withdraw plasma or cells from the patient's/donor's blood with a machine. Can be used to obtain plasma, platelets, or stem cells for transfusion; also to remove diseased plasma or excessive white cells

A method of obtaining and separating specific blood components, such as white blood cells (called leukopheresis), platelets, plasma, or stem cells. The process is similar to donating a unit of blood. During apheresis, a portion of the donor's blood travels through a closed, sterile tubing system through a machine that separates out the targeted cells and returns the remainder of the cells back to the donor.

The process of taking blood, cleansing it or adding certain substances, and returning the blood to the patient.

An automated method of separating platelets or plasma from the donor's blood and returning all but that component to the donor. Also known as Automated Blood Collection, or ABC.

A procedure to remove normal or abnormal white blood cells.

Procedure in which blood is taken from a donor, a blood component (such as white blood cells, red blood cells, or plasma) is separated out, and the remaining blood components are reinfused back into the donor.

A simple, painless process where blood is drawn from a patient's or donor's arm and circulated through a filter which removes stem cells from the blood. The rest of the blood is returned back to the patient or donor. Apheresis produces no side effects or discomfort for the blood stem cell donor. This is the procedure used for a Peripheral Blood Stem Cell (PBSC) Transplant.

a procedure in which blood is drawn and separated into its components by dialysis; some are retained and the rest are returned to the donor by transfusion

The process of removing components of a donor's blood and returning the unneeded parts to the donor. This process makes it possible to remove desired elements from large volumes of blood. Platelets, red cells, white cells, or plasma can be removed separately.

The collection of blood components from a patient or donor in which desired elements are removed and the remainder returned to the body.

A painless procedure, similar to a blood transfusion, designed to remove certain components of a person's blood, like platelets or stem cells, and return the remaining blood product back into the person's body.

A procedure in which blood is withdrawn, a specific portion(plasma, platelets, etc.) is separated and withheld, while the remainder is returned to the patient. MICRO GLOBULIN A protein that sheds off of dividing cells. It can be detected in the blood. In multiple myeloma, the higher the level the worse the prognosis.

A specialized form of blood extraction that can selectively isolate and remove particular components of the blood, returning the remainder of the blood to the patient.

A procedure in which blood is removed, a portion separated, and the remainder returned, often with replacement fluid. (See plasmapheresis.)

The technique of separating blood into its different components to collect a component.

The peripheral blood stem cell collection process in which blood is taken from a patient and circulated through a machine that separates out stem cells. The remaining cells are returned to the patient.

see hemapheresis

A blood-separating procedure in which blood is removed from a patient, sent through a special machine (where cells are separated and some are removed) and the remainder returned to the patient.

A procedure used to remove harmful substances from the blood.

a procedure in which blood is removed from a patient, certain fluid and cellular elements are removed, and the blood is then infused back into the patient.

a procedure in which a patient's own blood is removed, particular fluid and cellular elements are extracted from the blood, then returned to the patient.

the removal of a specific component of the blood for therapeutic purposes (e.g., plasmapheresis, or removal of plasma). Blood is removed, desired components are filtered out, and the remainder of the blood is returned to the body.

A special blood donation procedure in which plasma or selected cellular elements, such as platelets or white cells, are separated from the other parts of the blood and retained. Blood is drawn and processed through a cell separator, and the other cells and plasma are returned to the body. Apheresis takes approximately two hours compared with a whole blood donation of about eight to ten minutes.

A painless procedure by which blood is withdrawn from a patient's arm and circulated through a machine that removes certain components and returns the remaining components to the patient. This procedure is used to remove platelets from platelet donors' blood, or stem cells from patients undergoing a peripheral stem cell harvest.

A procedure in which blood is collected, part of the blood such as platelets or white blood cells is taken out, and the rest of the blood is returned to the donor. Also called pheresis.

A process in which blood is drawn outside the body, certain compounds are removed, and the blood is returned to the body. The technique has various applications, including: harvesting of needed components such as plasma or white blood cells; and removing harmful components such as large proteins, in order to treat the dry form of age-related macular degeneration (AMD). For more information, please see our article on age-related macular degeneration.

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.

The process of removing a specific component from blood and returning the remaining components to the donor , in order to collect more of one particular part of the blood than could be separated from a unit of whole blood. Also called hemapheresis or pheresis . See the entire definition of Apheresis

Apheresis (a-fur-E-sis) is the term used to apply to the collection of blood components: platelets, plasma and/or red cells. White cells are typically not collected because they are rarely transfused.

A procedure to collect peripheral blood cells by drawing blood and circulating it through a machine that removes the stem cells and returns the remaining blood cells to the person.

A procedure where blood is drawn from a patient's or donor's arm and circulated through a machine that removes certain cells such as stem cells, white blood cells or platelets. The rest of the blood is returned to the patient or donor.

The channeling of blood out of the body and through specialized single-use tubing and equipment in order to extract various blood cell types, such as platelets or stem cells, from the bloodstream. After these cells are extracted, the blood is returned to the body. Also called hemapheresis, or leukapheresis for the extraction of white blood cells.

Collection of peripheral blood stem cells by a device similar to a dialysis machine. The blood may be taken from a Hickman or other type of catheter or, if the patients veins are good, from the arms. Gathering enough cells for an autologous stem cell transplant may take from one to five days, depending on the amount of stem cells the patient has in their blood.

a procedure that circulates blood through a machine to remove cell components, for example, stem cells, platelets.

a procedure in which blood is drawn from a donor and separated into its components, some of which are retained, such as plasma or platelets, and the remainder returned by transfusion to the donor. Also called hemapheresis..

Any procedure in which blood is withdrawn from a donor, a portion (plasma, leukocytes, platelets, etc.) is separated and retained. The remainder is re-transfused into the donor. It includes leukapheresis, plateletpheresis, plasmapheresis, etc.

Retention of only needed components of blood for use and returning the remainder back to the donor.

A procedure where whole Blood is removed from the body and desired component(s), such as plasma or platelets is retained and the remainder of the Blood is returned to the donor.
