The process of removing a specific component from blood temporarily. Also known as hemapheresis and pheresis. Forms of apheresis include plasmapheresis, harvesting plasma or liquid part of the blood; leukapheresis, harvesting leukocytes or white blood cells; granulocytapheresis, harvesting granulocytes; lymphocytapheresis, harvesting lymphocytes; l [..]

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.

Process of removing a specific component from blood, such as platelets or white blood cells, and returning the remaining components to the donor; allows for more of one particular component to be collected than could be separated from a unit of whole blood

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.

Collection of peripheral blood cells, especially stem cells, by a device similar to a dialysis machine. Also see the Stem Cell Collection Page.

Any procedure in which Blood is withdrawn from a donor, a portion is separated and retained and the remainder is returned to the donor.

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.

The process in which blood is temporarily taken from the body, one or more parts of it removed, and the blood transfused back into the body.

 A procedure in which something is separated out, usually out of the blood; a special apparatus separates out one particular constituent of the blood (eg plasma, the liquid part of the blood, or cells such as stem cells) and returns the remainder of the blood to the circulation

<procedure> <haematology> A technique in which blood products are separated from a donor and the desired elements collected and the rest returned to the donor. This has the advantage of specificity and a good harvest, for example a good platelet collection may be obtained from two or three donors in which the conventional method would i [..]

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

Method of obtaining one or more blood components by machine processing of whole blood in which the residual components of the blood are returned to the donor during or at the end of the process.

A simple, painless process in which 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 [..]

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

A procedure in which blood is temporarily withdrawn, one or more components are selectively removed, and the remainder of the blood is re-infused into the donor.

The collection of a blood component, either cellular or non-cellular in composition, from the circulation.

a procedure in which blood is withdrawn from a donor, a portion is separated and retained (e.g.

Sometimes called leukapheresis, apheresis is a procedure in which blood is taken from a donor, circulated through the apheresis machine, which removes the fraction of the blood containing stem cells and returns the remaining fraction of the blood back to the patient.
