Apheresis Care

Apheresis Care

At the Siliguri Terai Lions Blood Centre, we are currently doing Apheresis in the form of Platelets (plateletpheresis).

It takes around 2 to 3 hours to donate platelets and this is equivalent to almost 8 to units of platelet concentrate.

This is extremely beneficial for the patients having a low platelet count, mostly in the cases of Dengue or Cancer.

Apheresis is a medical procedure that involves removing whole blood from a donor or patient and separating the blood into individual components so that one particular component can be removed. The remaining blood components then are re-introduced back into the bloodstream of the patient or donor. Apheresis is used for the collection of donor blood components (such a platelets or plasma) as well as for the treatment for certain medical conditions in which a part of the blood that contains disease-provoking elements is removed. Apheresis is also called pheresis or hemapheresis.The terminology used may also reflect the component of blood that is being removed, such as:

  • Plasma (plasmapheresis)
  • Platelets (plateletpheresis)
  • Leukocytes (leukapheresis or leukopheresis)
  • Lymphocytes (lymphopheresis or lymphapheresis)
  • Red blood cells (erythropheresis)

Total plasma exchange (removal of plasma and replacement with fresh frozen plasma) can also be performed using the apheresis procedure. It is also used for the collection of stem cells from the peripheral blood.

How is apheresis performed?

All apheresis procedures involve directing the blood in the patient/donor's veins through tubing to a machine that separates the blood components. The separation is done by either a centrifuge process or a filtration process on the blood in the machine. After the separation, the desired component of the blood is removed, while the remainder of the blood components are reinfused back into the patient. The entire procedure is painless and typically takes about two hours, or only slightly longer than a conventional blood donation.
